Complex Spatio - Temporal
We present the combination of microscopic model calculations and direct experimental evidence for complex spatio-temporal dynamics on a picosec-ond timescale in the near-eld of a broad area semiconductor laser induced by the interplay of self-focusing, diiraction, and spatial hole burning. We demonstrate the formation of migrating optical laments within the turn-on dynamics of such a laser and ...
متن کاملModulation Response and Relative Intensity Noise Spectra in Quantum Cascade Lasers
Static properties, relatively intensity noise and intensity modulation response in quantum cascade lasers (QCLs) studied theoretically in this paper. The present rate equations model consists of three equations for the electrons density in the conduction band and one equation for photons density in cavity length. Two equations were derived to calculate the noise and modulation response. Calcula...
متن کاملA Proposal for a New Method of Modeling of the Quantum Dot Semiconductor Optical Amplifiers
With the advancement of nanoscale semiconductor technology,semiconductor optical amplifiers are used to amplify and process all-optical signals. Inthis paper, with the aim of calculating the gain of quantum dot semiconductor opticalamplifier (QD-SOA), two groups of rate equations and the optical signal propagatingequation are used in the active layer of the device. For t...
متن کاملComplex spatio-temporal dynamics in the near-field of a broad-area semiconductor laser
– We present the combination of microscopic model calculations and direct experimental evidence for complex spatio-temporal dynamics on a picosecond timescale in the nearfield of a broad-area semiconductor laser induced by the interplay of self-focusing, diffraction, and spatial hole burning. We demonstrate the formation of migrating optical filaments within the turn-on dynamics of such a laser...
متن کاملBroadband semiconductor optical amplifiers and tunable semiconductor lasers
Nonidentical multiple quantum wells (MQWs) had been widely used for broadening the emission or gain bandwidth of semiconductor optical amplifiers (SOAs). However, the carrier distribution among the MQWs is not uniform, leading to nonuniform gain contributed from different QWs. Thus using nonidentical MQWs for broadband purpose is not intuitively straightforward. Several factors need to be caref...
