Abstract:
A bistable laser device comprising:a) a base distributed Bragg reflector, comprising alternating layers of at least two electrically conducting single crystal semiconductor materials; b) a base electrical terminal functionally attached to the base distributed Bragg reflector; and, c) at least two laser cavity structures disposed in a vertical stack above the base distributed Bragg reflector, each of said laser cavity structures having a resonance wavelength and comprising; 1) an active laser medium stratum; 2) a laser cavity distributed Bragg reflector positioned above the active laser medium stratum, such that the laser cavity distributed Bragg reflector comprises alternating layers of at least two electrically conducting single crystal semiconductor materials; and, 3) a laser cavity electrical terminal functionally attached to the laser cavity distributed Bragg reflector.
