• ### Impact of Mode-Hopping Noise on InGaN Edge Emitting Laser Relative Intensity Noise Properties

Publication Year: 2018, Article Sequence Number: 1100107
| | PDF (1273 KB) | HTML

In this paper, we report, through a comparative analysis of static and dynamic measurements, on the impact of mode hopping on the overall intensity noise dynamics of InGaN edge emitting lasers. Mode clustering usually observed in InGaN lasers enhances the mode competition and then the laser intensity fluctuation. Variations as large as 20 dB have been observed. The coexistence of longitudinal mode... View full abstract»

• ### FPGA-Based Optical Cavity Phase Stabilization for Coherent Pulse Stacking

Publication Year: 2018, Article Sequence Number: 1600111
| | PDF (3332 KB) | HTML

Coherent pulse stacking (CPS) is a new time-domain coherent addition technique that stacks several optical pulses into a single output pulse, enabling high pulse energy from fiber lasers. We develop a robust, scalable, and distributed digital control system with firmware and software integration for algorithms, to support the CPS application. We model CPS as a digital filter in the Z domain and im... View full abstract»

• ### A New Method of Diagnostics of the Quality of Heavily Yb-Doped Laser Media

Publication Year: 2018, Article Sequence Number: 1700106
| | PDF (1495 KB)

A new method of optical material diagnostics by measuring the heat release under illumination is proposed. Narrowband radiation triggers certain mechanisms of heating, while direct temperature measurement allows obtaining the amount of heat release in the medium. The mechanisms of heat production in heavily doped Yb:YAG crystals grown by different techniques are investigated using the new method. ... View full abstract»

In this paper, we investigate the noise performance and transfer in a titanium sapphire (Ti:S) laser system. This system consists of a distributed Bragg-reflector tapered diode laser, which is frequency doubled in two cascaded nonlinear crystals and used to pump the Ti:S laser oscillator. This investigation includes electrical noise characterizations of the utilized power supplies, the optical noi... View full abstract»

• ### Wavelength Blue-Shifting and Gain Spectral Bandwidth of InAs/InP Quantum Dots for Laser Applications Around $1.55~mu$ m

Publication Year: 2018, Article Sequence Number: 2000109
| | PDF (1899 KB) | HTML

It was found experimentally that growing an ultrathin GaP interlayer/sublayer before InAs quantum dots (QDs) grown on InGaAsP barrier lattice-matched to InP (001) substrates is an efficient way to tune the emission wavelength of InAs/InP QD lasers to 1.55 μm range at room temperature (RT). However, the impact of interlayers/sublayers in InAs/InP QD lasers has not been carefully investigated... View full abstract»

• ### Stochastic Differential Equation Model for Spontaneous Emission and Carrier Noise in Semiconductor Lasers

Publication Year: 2018, Article Sequence Number: 2000206
| | PDF (204 KB)

We present a new stochastic differential equation model for the spontaneous emission noise and carrier noise in semiconductor lasers. The correlations between these two types of noise have often been neglected in recent studies of the effects of the noise on the laser dynamics. However, the classic results of Henry show that the intensity noise and the carrier noise are strongly negatively correla... View full abstract»

• ### Information-Theory-Based Complexity Quantifier for Chaotic Semiconductor Laser With Double Time Delays

Publication Year: 2018, Article Sequence Number: 2000308
| | PDF (1574 KB)

The complexity properties of the chaotic signals generated by a chaotic semiconductor laser (SL) with double time delays are quantified numerically. A modified complexity quantifier, mean permutation entropy (MPE), based on information theory, is applied to fully characterize the chaotic complexity. The autocorrelation time (ACT) is also employed as a supplement quantifier. The numerical analyses ... View full abstract»

• ### Factors Determining the Carrier Distribution in InGaN/GaN Multiple-Quantum-Well Light-Emitting Diodes

Publication Year: 2018, Article Sequence Number: 3200107
| | PDF (1030 KB) | HTML

Factors determining the carrier distribution in InGaN/GaN multiple-quantum-well (MQW) light-emitting diodes (LEDs) are studied via photoluminescence, temperature-dependent electroluminescence spectra, and numerical simulations. Employing a dichromatic LED device, we demonstrate that the carrier recombination rate should be considered playing an important role in determining the carrier distributio... View full abstract»

• ### Optimization Study of a Novel Few-Layer Graphene/Silicon Quantum Dots/Silicon Heterojunction Solar Cell Through Opto-Electrical Modeling

Publication Year: 2018, Article Sequence Number: 4800106
| | PDF (1507 KB) | HTML

Few-layer graphene/silicon quantum dots/silicon (FLG/SiQDs/Si) heterojunction solar cells consisting of a layer of SiQDs sandwiched between FLG and p- or n-type Si is examined by a device physics model incorporated with the optical characteristics of FLG and SiQDs. FLG/SiQDs/Si solar cells enhance short-circuit current density, because charge carriers can tunnel through the energy states in SiQDs.... View full abstract»

• ### Dynamics of Optoelectronic Oscillators With Electronic and Laser Nonlinearities

Publication Year: 2018, Article Sequence Number: 5000207
| | PDF (661 KB) | HTML

We present a theoretical and experimental study of a low-frequency optoelectronic oscillator featuring both laser-diode and Van der Pol-like nonlinearities. In this architecture, the device performing the electrical-to-optical conversion is the laser-diode itself instead of an external electro-optical modulator, while the electric branch of the oscillator is characterized by a Van der Pol nonlinea...

• ### A High-Order Symplectic FDTD Scheme for the Maxwell-Schrodinger System

Publication Year: 2018, Article Sequence Number: 6100108
| | PDF (1550 KB)

In the finite-difference time-domain simulation of the Maxwell-Schrodinger system it is necessary to analyze multi-physics phenomena ruled by more than one governing equation. In this paper, a novel approach was proposed to solve the hybrid simulation. Using fourth-order spatial differences for the whole system and third-order symplectic integrators for the Schrodinger equation, the simulation was... View full abstract»

• ### Mode Coupling and Scattering Parameters in a Parity-Time Symmetric Resonant Integrated Coupler

Publication Year: 2018, Article Sequence Number: 6300206
| | PDF (641 KB)

We investigate theoretically, in the frame of coupled-mode theory, a parity-time symmetric directional coupler inserted into a symmetric resonant cavity, all ports being terminated by four identical lossless reflectors. The scattering parameters are expressed under analytic closed forms in several equivalent bases, underlining the fact that PT Symmetry can be thought of as mode coupling between th...

| | PDF (1861 KB)

Characteristics- and polarization-dependences of the transmission spectrum for a consecutively cascaded single-helix long-period fiber gratings with opposite helicities (CC-SHLPGs-OH) have been comprehensively analyzed for the first time. It has been found that the TE/TM cladding mode produced in the first single-helix long-period fiber grating (SHLPG) will largely affect the mode couplings in the... View full abstract»

• ### Spectral Control of Near-Field Thermal Radiation With Periodic Cross Resonance Metasurfaces

Publication Year: 2018, Article Sequence Number: 7000107
| | PDF (2047 KB) | HTML

Near-field thermal spectra can be engineered using periodic cross resonance metasurfaces. Structures consisting of single crosses, double crosses, and multiple crosses are proposed to control the spectral heat flux from narrow band to broadband with the Fabry-Pérot-cavity-like effect and the interaction between the emitter and receiver. Radiation peaks originating from the cross structures... View full abstract»

The frequencies for thirty one far-infrared laser emissions, generated by an optically pumped molecular laser with either 13CD3OH or CH318OH as its laser medium, have been measured for the first time. The frequencies, ranging from 0.443 to 3.243 THz, were measured with a heterodyne technique to a one-sigma fractional uncertainty no less than ± 5 parts in 107... View full abstract»

Femtosecond (fs-) laser induced subwavelength and deep-subwavelength periodic structures have attracted attention due to their sub-diffraction feature size and rich physics of laser-matter interaction. However, the formation mechanisms of fs-laser induced deep-subwavelength structures on organic materials have not been reported nor systematically studied. Herein, based on the degree of laser induc... View full abstract»
