Frequency selectivity in laterally coupled semiconductor laser arrays.
A longitudinal-mode analysis of a system of laterally coupled waveguided resonators is presented in the coupled-mode approximation. It is shown that variations in the mirror reflectivity of the individual channels result in coupling between the supermodes of the structure. This may lead to mode suppression by modulation of the threshold gain of different Fabry-Perot modes.
متن کاملAdvances in semiconductor laser bars and arrays
Advances in high power semiconductor lasers such as increased spectral brightness, increased spatial brightness, and reduced cost architectures at wavelengths from the near infrared to the eye-safe regime have the potential to dramatically improve diode pumped systems and enable new direct diode applications. Data are presented which demonstrate both edge emitter devices and high power surface ...
متن کاملRate Equations Analysis of Phase-Locked Semiconductor Laser Arrays Under Steady State Conditions
Rate equations analysis of phase-locked semiconductor laser arrays has been carried out. I t was found that for given (laser) current densities, the photon density distribution in the array elements is that pmticular one which maximizes the total photon density. Theresults of this analysis were then combined with the waveguiding properties of the laser array waveguide, yielding a basic model of...
متن کاملTurbulent chimeras in large semiconductor laser arrays
Semiconductor laser arrays have been investigated experimentally and theoretically from the viewpoint of temporal and spatial coherence for the past forty years. In this work, we are focusing on a rather novel complex collective behavior, namely chimera states, where synchronized clusters of emitters coexist with unsynchronized ones. For the first time, we find such states exist in large diode ...
متن کاملParallel Simulation of Semiconductor Laser Arrays
A parallel Hopscotch algorithm for the simulation of semiconductor laser arrays which overlaps the computations and communications is presented. The method uses a Lax-Wendroff scheme for the hyperbolic part of the operators and allows to obtain near-to-perfect speed-ups on MIMD computers. Numerical experiments indicate that semiconductor laser arrays exhibit a rich dynamic behavior ranging from...
