Optical phase conjugation laser diode

Abstract

A phase-conjugating resonator that includes a semiconductor laser diode apparatus that comprises a phase-conjugating array of retro-reflecting hexagon apertured hexahedral shaped corner-cube prisms, an electrically and/or optically pumped gain-region, a distributed bragg reflecting mirror-stack, a gaussian mode providing hemispherical shaped laser-emission-output metalized mirror. Wherein, optical phase conjugation is used to neutralize the phase perturbating contribution of spontaneous-emission, acoustic phonons, quantum-noise, gain-saturation, diffraction, and other intracavity aberrations and distortions that typically destabilize any stimulated-emission made to undergo amplifying oscillation within the inventions phase-conjugating resonator. Resulting in stablized high-power laser-emission-output into a single low-order fundamental transverse cavity mode and reversal of intra-cavity chirp that provides for high-speed internal modulation capable of transmitting data at around 20-Gigabits/ps.

1 . An optical phase conjugating laser diode, comprising:
 a) a stimulated-emission source of photons, defining a gain-medium for the optical phase conjugating resonant-cavity of said laser;   b) providing for an optical feedback, using a pseudo phase-conjugating corner-cube array as first reflector, a distributed bragg mirror-stack as second reflector, and a gaussian mode providing laser-emission-mirror as third reflector, defining a fundimental transverse mode for said cavity of said laser;   c) providing for an electrical pumping source, defining an energy source for pumping said gain-region of said laser,   whereby, said phase-conjugation provides for a high-power laser-emission-output into a single fundamental transverse spatial cavity mode of said cavity, and   whereby, said phase-conjugation provides for a neutralization of the perturbation causing contribution of spontaneous emission.
