Abstract:

Recently, much more attention has been directed to diode-pumped single-longitudinal-mode (SLM) fiber lasers because of their high reliability, compactness, and capability of shot-noise-limited operation in the megahertz frequency range. On the other hand, tunable laser sources have seen various applications in recent years such as optical switching, network protection or digital communication. Among various lasers, fiber lasers present the advantages of high brightness, low intensity noise, thermal stability, excellent coupling into a single mode fiber and better compatibility with fiber components. In this talk, we will review and discuss several types of single-longitudinal mode (SLM) linear cavity, tunable fiber lasers, either in C+L band or 1064 nm band. For linear-cavity fiber laser schemes, the elements may base on a loopback optical circulator (OC), a broadband mirror, a Faraday rotator mirror or a 2x2 fiber coupler integrated a partial reflectance fiber Bragg grating (FBG) as the front cavity end. For SLM selection, using multiple subring cavities based on the Vernier effect, a piece of gain fiber saturable absorber as modes filter or their hybrid type. For wide-tuning range fiber laser, the wavelength tuning mechanism include the use of a broadband fiber mirror (BFM) integrated tunable FBGs as cavity ends, using bending device to facilitate wavelength tuning of FBG, a large tuning range cover C+L band with good resolution of 0.1 nm is obtained. Laser characteristics such as output, signal-to-noise ratio, linewidth, threshold pump power, pumping slope efficiency and side mode suppress ratio are measured. One example of fiber laser characteristics are 1 MHz, 59 dB, 13% and 0.1 dB, respectively, for linewidth, side-mode suppression ratio, quantum efficiency and power variation of whole tuning range. The pumping power efficiency may be improved more than 10% by recycling the residual pump power to the gain medium. Have the advantages of simpler structure, larger pump slope efficiency and shorter cavity, these fiber lasers may find potential applications in various ways.

The keynotes present a historical analysis of scientific achievements, essential events in physics, deep logics in sciences, and philosophy of consensus. A critical re-evaluation of our knowledge is the start of a new way to a new era, the revolution of theoretical science and the return of philosophy: Back to the Future. Mankind has been furnished with groundbreaking enlightenment of the demonstrated theories of our universe: Duality of physical and virtual worlds, revealing Elementary Particles and Unified Field Theory according to concise, systematic, philosophical and mathematical principles. The year 2015, therefore, bids farewell to an intellectual age of classical physics defined by mathematical empiricism, from Newton's Mechanics of 1687 to Einstein’s Relativity of 1915, and from Quantum Theory of 1920s to contemporary physics. rnrnToday, human society is at the dawn of a series of revolutions for a new era:rn1. Advancing scientific philosophies to the next generation,rn2. Standardizing topological frameworks for modern physics,rn3. Developing information technologies through virtual reality,rn4. Theorizing biology and biophysics in innovative life sciences,rn5. Reformulating metaphysics on the basis of scientific naturalism.rnrnOur challenge, however, is even greater. It is the challenge to open up the world to facts hidden in the fabric of daily life, the challenge to transcend metaphysical prejudices and the ignominious clamor of hype. As a scientist, you may find youself in pioneering our human revolution. rn

His recent publications in JMP, Physics Letters and Foundations of Physics are dedicated to finding a bridge between classical and quantum physics and gravity.

Abstract:

A recently proposed mathematical framework that unifies the standard formalisms of classical mechanics, relativity and quantum theory will be presented. In the framework, states of a classical particle are identified with Dirac deltas. The classical space is "made" of these functions and becomes a sub-manifold in a Hilbert space of states of the particle. The resulting embedding of the classical space into the space of states is highly non-trivial and accounts for numerous deep relations between classical and quantum physics and relativity. One of the most striking results is the proof that the normal probability distribution of position of a macroscopic particle (equivalently, position of the corresponding delta state within the classical space sub-manifold) yields the Born rule for transitions between arbitrary quantum states.

Abstract:

The non-zero thickness of transition metal dichalcogenide (TMDC) single layer (SL) manifests in electron states forming classes of states even and odd with respect to reflections through the central plane. These states are energetically well separated and give rise to two bandgaps Eg|| and Eg for the optical in-plane and out-of-plane susceptibilities || and , respectively. Because of this, odd states are often neglected, which effectively reduces TMDC SL to a perfect 2D system. We study states bound to various vacancy defects in TMDC SL and show that odd states play an equally important role as even states. In particular, we show that odd states bound to VD lead to resonances in  inside Eg in TMDC SL with VDs. Additionally, we demonstrate that the states bound to VDs are not necessarily confined to the bandgap in the even subsystem, which requires the extension of the energy region affected by the bound states. The resulting optical signatures not only provide the possibility to identify the type but also the concentration of VDs, thereby paving the way to quantifying the purity of defected TMDC SL containing VDs.

Abstract:

Electron density oscillations in the transistor channels - plasma waves in the two-dimensional electron gas - determine the high frequency device response. Plasmonic field effect transistors have emerged as very sensitive, tunable, and extremely fast detectors of THz radiation. They have been implemented using silicon (CMOS), AlGaAs/InGaAs HEMTs, and AlGaAs/InGaAs HEMTs, with the HEMTs shown to operate more efficiently at higher THz frequencies. These HEMTs have both gated and ungated sections of the device channel between the source and drain, and the photovoltaic regime of operation requires an asymmetric gate placement in the device channel. The interactions of the plasma waves in the gated and ungated channel regions strongly affect the overall response and have been investigated in numerous publications. This work addresses a new aspect of such interaction - the effect of the relative position of the gated and ungated section. We show this previously unexplored effect plays a dominant role in determining the response. The results of the numerical simulation based on the solution of the complete system of the hydrodynamic equations describing the electron fluid in the device channel show that the inverse response frequency could be approximated by the sum of the gated plasmon transit time in the gated section of the device, the ungated plasmon transit time in the ungated section of the device between the gate and the drain, and the RC gate-to-source constant. Here R and C are the resistance and capacitance of the gate to source section. Hence, the highest speed is achieved when the gate is as close to the source as possible. This suggests a novel plasmonic detector design, where the gate and source electrode overlap, which is shown to have a superior frequency response for the same distance between the source and the drain.

Abstract:

The study of non-uniform obstacles in an otherwise uniform waveguide has received wide attention in the literature. The transmission of elastic and electromagnetic waves, underwater sound propagation, and sound scattering in ducts or pipes are the major application areas in waveguide theory. Particularly the curiosity is to reduce the ducted fan noise emanated from aero engines, power stations and heating, ventilation, and air conditioning (HVAC) systems. There are several mathematical models exist for computing sound attenuation by such dissipative devices which are often used to attenuate broadband noise arising from fluid moving devices likewise fans and internal combustion engines. In this study we aim to investigate theoretically the mode-matching analysis of a two dimensional waveguide problem subject to rigid and flexible walls. The governing mathematical model characterizes the system to be non Sturm-Liouville. Therefore the development of generalized orthogonality relations corresponding to acoustic transmission through the duct regions is the major necessity to find out solution. Also appropriate edge conditions including, clamped and pin-jointed are considered in order to guarantee the uniqueness of solution. We investigate amplitudes of reflection and transmission coefficients along with power distribution for each duct region. The aims of this study were to assess distribution of power through the fluid regions and the flexible wall using different edge conditions. In order to see the accuracy of results the truncated system is verified through the matching interface conditions and the power balance as well. In this way the mode-matching technique proves to be surprisingly accurate and is a useful tool for solving acoustic structural problems.

Abstract:

For the first time in mankind history, the natural laws of our universe is uncovered systematically, philosophically and mathematically, which convey the principles of YinYang movement governing all physical events, transforming universe particles, and constituting extendable physical hierarchies. It develops the dynamic fields, called Horizon Fields, which form and give rise to physical horizons: From inception of time, energy, mass, and space, to elementary particles, to quantum fields, to thermodynamics, to electromagnetism, gravitational force, and beyond. These applications of the evolutionary processes to contemporary theoretical physics therefore derive a complete picture of the principal equations, important assumptions, and essential laws, promoting scientific research to the next level by: 1. Delivering the terminology for a topological framework of cosmology aligned with the synthesis of virtual and physical worlds in a hierarchical taxonomy of the universe, 2. Describing full-scale properties for all fundamental particles, including quarks, leptons, bosons, dark energy, and composite particles, and their entire nature formation of physics, 3. Delineating YinYang physics as a foundation of Cosmology, Quantum Physics, Astrology, and Biophysics across all mass and matter. Intuitively following the system of YinYang philosophy, this concise theory is accessible and replicable by readers with a basic background in mathematical derivation for theoretical physics.
