Modeling bidirectionally coupled single-mode semiconductor lasers
We develop a dynamical model suitable for the description of two mutually coupled semiconductor lasers in a face-to-face configuration. Our study considers the propagation of the electric field along the compound system as well as the evolution of the carrier densities within each semiconductor laser. Mutual injection, passive optical feedback, and multiple reflections are accounted for in this...
متن کاملMode Competition in Gas and Semiconductor Lasers
The output spectrum of both gas and semiconductor lasers usually contains more than one frequency. Multimode operation in gas versus semiconductor lasers arises from different physics. In gas lasers, slow equilibration of the electron populations at different energies makes each frequency an independent single-mode laser. The slow electron diffusion in semiconductor lasers, combined with the sp...
متن کاملMode Synchronization of External Cavity semiconductor Lasers
In the last 20 years external cavity semiconductor lasers (ECSLs) have been the subject of extensive research due to their importance for technical applications like optical fiber communications. One of the most detailed investigated dynamical phenomenon occurring in ECSLs are low frequency fluctuations (LFFs) [Fischer et al., 1996; Fischer et al., 1998]. The intensity of the laser oscillates a...
متن کاملMode Profiling of Semiconductor Nanowire Lasers.
We experimentally determine the lasing mode(s) in optically pumped semiconductor nanowire lasers. The spatially resolved and angle-resolved far-field emission profiles of single InP nanowire lasers lying horizontally on a SiO2 substrate are characterized in a microphotoluminescence (μ-PL) setup. The experimentally obtained polarization dependent far-field profiles match very well with numerical...
متن کاملModelling colliding-pulse mode-locked semiconductor lasers
A discussion of three topics in the eld of non linear optics is presented We begin with the Colliding Pulse Mode locked CPM Quantum Well QW laser A large signal model consisting of a wave propagation equation for the electrical eld and a rate equation model for the material response is derived The wave propagation equation of the electrical eld is derived from Maxwell s equations in the slowly ...
