Abstract:

We have recently demonstrated large two beam coupling gains in indium phosphidesiron by combining the band-edge resonance technique with a second resonant enhancement involving temperature stabilization.1 While loss increases near the band-edge, the gain increases much more dramatically. Net gain coefficients larger than 20cm have been measured making semiconductor gains comparable to those in ferroelectric materials. We present here an investigation of this material as a self pumped phase conjugator.
