Spin Laser Local Oscillators for Homodyne Detection in Coherent Optical Communications
We numerically investigate spin-controlled vertical-cavity surface-emitting lasers (spin-VCSELs) for local oscillators, which are based on an injection locking technique used in coherent optical communications.

Image Transmission Based on Spiking Dynamics of Electrically Controlled VCSEL-SA Neuron
Based on the spiking dynamics of the electrically controlled vertical-cavity surface-emitting laser with an embedded saturable absorber (VCSEL-SA), we propose an image transmission system using two unidirectionally coupled VCSEL-SAs and numerically ...

A buried tunnel junction 940 nm VCSEL for achieving thermal diffusion characteristics
To investigate the performance degradation of a vertical-cavity surface-emitting laser (VCSEL) caused by self-heating effects, a 940 nm VCSEL with a buried tunnel junction (BTJ) and an aperture size of 10 μm was designed. The BTJ-type VCSEL achieves a 39.
