Several parameters are proposed for describing the statistical thermodynamic component of the exchange of photons between a pump and a laser beam. They are based on the occupation probability of absorbing and emitting, pump and laser levels, and are complementary to the optical cross sections. The ldquooccupation factor,rdquo f 0 , is appropriate for describing an optical amplifi... View full abstract»

• ### Electronic Stabilization of Continuous-Wave and Pulsed Lasers Based on Macroscopic Rate-Equation Modelling

Publication Year: 2009, Page(s):1221 - 1231
| | PDF (1059 KB) | HTML

We present a macroscopic laser rate-equation model based on measurable laser parameters, allowing easy system identification. A numerical simulation based on the model is used in the design and testing of electronic laser feedback systems for intensity noise suppression and Q-switched pulse stabilization. A novel pulse energy control scheme is also presented, including experimental results. View full abstract»

The reciprocity relation of McCumber which states that the emission and absorption spectra of broad solid-state laser transitions are related by the classical Boltzmann factor is critically examined. It is argued that it should be treated as an exact property of homogeneously broadened amorphous host gain media at room temperature. The contradiction between these conclusions and those of recent li... View full abstract»

• ### Optical Noise Tolerance in a Polarization-, Wavelength-, and Filter-Free All-Optical Clock Recovery System Based on a Monolithic Mode-Locked Laser

| | PDF (1173 KB) | HTML

We experimentally investigated optical noise tolerance of a polarization-, wavelength-, and filter-free all-optical clock recovery system based on a monolithic mode-locked laser diode. The results showed that for input signal degradation, the jitter of the recovered clock did not degrade to approximately 8 dB/nm of the optical SNR. We also compared the clock recovery performance as functions of th... View full abstract»

• ### Effective Noise Reduction by Electric Positive and Negative Feedback in Semiconductor Lasers

Publication Year: 2009, Page(s):1248 - 1254

| | PDF (520 KB) | HTML

Semiconductor lasers tend to generate excess intensity noise called the optical feedback noise in addition to the quantum noise. A noise reduction method using an electric positive and negative feedback loop between an optical detector and a semiconductor laser was demonstrated in this paper. The electric positive feedback was set in a high-frequency region, reducing the optical feedback noise, wh... View full abstract»

Corrugated quantum-well infrared photodetectors (C-QWIPs) have been proposed for long-wavelength infrared detection. In this work, we optimize the detector structure and produce a number of large format focal plane arrays (FPAs). Specifically, we adopt one-corrugation-per-pixel geometry to increase the active detector volume and incorporate a composite cover layer to preserve the large sidewall re... View full abstract»

A study of the threshold characteristics of quantum-dot (QD) laser diodes shows how inhomogeneous broadening and p-doping influence the QD laser's temperature dependence of threshold T 0. The analysis includes the additional parameters of homogeneous broadening, quantum state populations, and threshold gain. The results show that while the source of negative T 0...

• ### Theoretical Investigation of the Radiation Pattern From LEDs Incorporating Shallow Photonic Crystals

Publication Year: 2009, Page(s):1273 - 1283

| | PDF (1048 KB) | HTML

A theoretical approach based on coupled-mode theory is presented in order to determine the radiation pattern of LEDs incorporating a shallow photonic crystal. From this, a fundamental limit for the directionality of the diffraction of a single guided mode is given. Additionally, the Fabry-Perot resonances are shown to have significant impact on the directionality of diffracted light. For a realist... View full abstract»

• ### Position Effect of Spectral Filter on Properties of Highly Chirped Pulses in an All-Normal-Dispersion Fiber Laser

Publication Year: 2009, Page(s):1284 - 1288

| | PDF (591 KB) | HTML

Numerical studies on the position effect of spectral filter (SF) in an all-normal-dispersion fiber laser are presented in this paper. The dependence of the available bandwidth range of the SF on its position in the laser cavity is investigated. Our simulation results suggest that the output pulses with high energy and strong peak power can be obtained when the SF with an appropriate spectral bandw... View full abstract»

• ### Reducing ASE Effect in Coherent Detection by Employing Double-Pass Fiber Preamplifier and Time-Domain Filter

Publication Year: 2009, Page(s):1289 - 1296
| | PDF (447 KB) | HTML

We report on a novel fiber based coherent detection system employing a double-pass fiber preamplifier, a spectral bandpass filter, and a time-domain filter. The time-domain filter, a synchronous time gate, reduces the in-band amplified spontaneous emission (ASE) beat noise, which cannot be achieved by the spectral bandpass filter alone. The double-pass fiber amplifier further reduces the out-band ... View full abstract»

• ### Analytical Solution of Band Gaps in 2-D Photonic Crystals Made by Multi-Beam Interference

| | PDF (227 KB) | HTML

Analytical solution of band gaps in two-dimensional (2-D) photonic crystals made by multi-beam interference was put forward. This solution gives concise analytical expression of every band gap. The quantitative relationship between the characters of band gaps and parameters of the materials of 2-D PC is different from that of one-dimensional (1-D) PC. For structures satisfying some conditions, the... View full abstract»

Minch [IEEE J. Quantum Electron., vol. 35, no. 5, pp. 771-782, May 1999] compared the theoretical conduction band offset ratio of In1-x-yGaxAlyAs/InP heterostructure calculated from Harrison's model and model-solid theory to the empirical results obtained from experimental measurement. We wish to point out that the comparison was not appropriate as the calculated r... View full abstract»
