The dynamics of injection-locked vertical-cavity surface-emitting lasers (VCSELs) are studied as a function of temperature. The temperature dependence of the slave VCSEL's parameters is used in a rate-equation analysis and parametric maps in the injection strength K- and frequency detuning ω-planes are calculated in order to investigate the temperature dependence of the system's stability.

We report the observation of stable pulse emission and enhancement of intracavity second-harmonic generation (SHG) in self-mode-locked quantum cascade (QC) lasers. Down-conversion of the detector signal by heterodyning with an RF signal allows the direct observation of the pulsed laser emission in the time domain and reveals a stable train of pulses characteristic of mode-locked lasers. The onset ... View full abstract»

• Subharmonic pulse-gating in self-seeded laser diodes for time- and wavelength-interleaved picosecond pulse generation

| |PDF (352 KB) | HTML

A new approach of generating high-repetition-rate picosecond pulses at sequentially switching wavelengths has been proposed and experimentally demonstrated. The approach is based on subharmonic pulse-gating and self-seeding of a single Fabry-Perot laser diode. Output of up to ten wavelengths at a repetition rate of 10 GHz has been achieved. The output exhibits a relatively uniform power across the... View full abstract»

A dispersion-managed breathing-mode mode-locked semiconductor ring laser is studied. The working regime and pulse evolution at the key cavity points are experimentally characterized and numerically simulated. Linearly chirped, asymmetric exponential pulses are generated and externally compressed to 274 fs, which is within 10% of the bandwidth limit. The close agreement between the simulated and th...

• Galerkin method for calculating valence-band wavefunctions in quantum-well structures using exact envelope theory

Publication Year: 2004, Page(s):222 - 230

| |PDF (248 KB) | HTML

The ability to calculate accurately the valence-band structure in semiconductors is important in the design of quantum-well (QW) semiconductor devices. The Galerkin method for calculating accurate analytic approximations for multicomponent valence-band wavefunctions is computationally fast and efficient. The Galerkin method is, in fact, an improved version of an earlier Raleigh-Ritz-type variation... View full abstract»

• Feedback sensitivity and coherence collapse threshold of semiconductor DFB lasers with complex structures

A general method for evaluating the feedback sensitivity of semiconductor lasers is proposed based on Green's functions approach. The rate equations derived in this paper generalize works already published to any type of laser cavities such as those with axially varying parameters. The variation of the lasing frequency occurring under external optical feedback is then used to predict the coherence... View full abstract»

• Degradation of the mode suppression in single-mode laser diodes due to integrated optical amplifiers

Publication Year: 2004, Page(s):241 - 244

| |PDF (296 KB) | HTML

We show that the side-mode suppression in single-mode laser diodes, such as DFB or distributed Bragg reflector laser diodes, can be reduced by 10 dB or more if an optical amplifier is integrated with the laser diode. The reduction of the side-mode rejection is due to an increase of spontaneous emission that couples into the side mode, an increase which in turn is due to amplified spontaneous emiss...

• Noise and regeneration in semiconductor waveguides with saturable gain and absorption

We have modeled the noise properties of a novel waveguide device with regenerative properties. The device consists of alternating sections of saturable gain and absorption, which give a nonlinear power transfer function. We investigate the relative intensity noise spectra and signal-to-noise ratio after the device by both a small-signal analysis and large-signal simulation, and we show that the ga...

A novel cascaded second-order nonlinear interaction (χ(2)), which is simultaneously based on sum frequency generation (SFG) and difference frequency generation (DFG) processes, is proposed and analyzed in quasi-phase-matched wavelength converters. Analytical expressions with clear physical insights are derived for the converted light. It is shown that the same conversion efficiency ... View full abstract»

We have demonstrated the feasibility of cooling high-power solid-state lasers with diamond windows, whose thermal conductivity is about two orders of magnitude higher than that of sapphire. An output power of 200 W was achieved from a single Nd:YVO4 slab in a zigzag configuration when pumped with 600-W diodes at 808 nm. The maximum output power previously reported in the literature usin... View full abstract»

| |PDF (328 KB) | HTML

Novel models for the saturation factors of absorption under optical pumping in solid-state lasers are derived, and these factors depend on the pumping scheme. We investigated the pump saturation effect in Nd:YVO4 and found that the bleaching of pump absorption due to the depletion of a ground-state level in a direct pumping scheme was more effective than that in a conventional four-leve...

We have developed a prepulse-free short-pulse Nd:glass laser system of 0.9-PW peak power to heat a pre-imploded high-density plasma. An optical parametric chirped amplification system is introduced to reduce the prepulses to an amplitude (1.5×10-8) of that of the main pulse.

We describe a new optoelectronic device with time-delayed feedback that uses a Mach-Zehnder interferometer as passive nonlinearity and a semiconductor laser as a current-to-optical-frequency converter. Band-limited feedback allows tuning of the characteristic time scales of both the periodic and high dimensional chaotic oscillations that can be generated with the device.

A theory for pulse amplification and saturation in quantum dot (QD) semiconductor optical amplifiers (SOAs) is developed. In particular, the maximum bit rate at which a data stream of pulses can be amplified without significant patterning effects is investigated. Simple expressions are derived that clearly show the dependence of the maximum bit rate on material and device parameters. A comparative... View full abstract»

We report suppression of edge breakdown in mesa-structure SiC avalanche photodiodes (APDs) by employing a 10° sidewall bevel. These devices exhibit low dark currents, <10 pA for a 160-μm-diameter device, at the onset of avalanche gain. Two-dimensional raster scans of both beveled and nonbeveled devices, fabricated from the same wafer, show the photocurrent as a function of position and illu... View full abstract»

The surface-plasmon-polaritons supported by a metal stripe are of theoretical and experimental interest. The well-known symmetric and antisymmetric modes of the slab model become the respective fundamental modes of the stripe. Their dispersion and loss characteristics are calculated for a silver stripe embedded in silicon. In contrast to the slab case, higher order modes also occur for the stripe.... View full abstract»
