A model is presented for optically controlling the gain of a semiconductor laser by introducing photons from a second coherent source into the side of the laser. We find that the threshold current of the laser increases in direct proportion to the ov

We report the experimental demonstration of monolithic all-optical 1:N routing switches using CW gain-quenched, intracavity-coupled in-plane and vertical cavity surface emitting lasers (VCSELs) as the switching elements. These optically-coupled laser

An in situ laser reflectometer is used to determine the surface roughness of III–V laser heterostructure as it etches in an electron cyclotron resonance etcher. A stochastic model links the reflectometer signals with the fluctuations of the surface
