Image sensitive spectral response of semiconductor random network lasers

Kirsten Emilie Moselund

We experimentally study the spectral lasing response of on-chip InP network random lasers under illumination of different input image shapes. Deep-learning models have become increasingly omipresent throughout society. However, they are blighted by exponen ...

Wafer-Fused 1310 nm and 1550 nm Mode-Locked Semiconductor Disk Lasers

Elyahou Kapon, Alexandru Mereuta, Alexei Sirbu, Vladimir Iakovlev, Andrei Caliman

We report on fabrication and performance of wafer fused, high power, passively mode-locked semiconductor disc lasers operating in 1310 nm and 1550 nm bands. These devices comprise gain mirrors based on InAlGaAs/InP multi quantum well active regions fused t ...
