Second, there's the semiconductor mirror used in the laser – called a Semiconductor Saturable Absorber Mirror or SESAM. It helps shape the laser light into short, intense pulses. This was upgraded by ...

Shaanxi Joint Laboratory of Graphene, State Key Laboratory of Photon-Technology in Western China Energy, International Collaborative Center on Photoelectric Technology and Nano Functional Materials, ...

Here, we present a theoretical investigation of a neuromorphic photonic system based on a vertical cavity surface emitting laser with an embedded saturable absorber (VCSEL-SA). The primary objective ...

The second innovation regards the centrepiece of the pulsed laser: a special mirror made of semiconductor material, which was invented by Keller 30 years ago , known as SESAM (Semiconductor Saturable ...
