Guided-wave optical bistability in indium antimonide thin films

Various grating configurations used to obtain optical bistability in a guided-wave format are discussed and experimentally demonstrated using indium antimonide planar waveguides. The theory of nonlinear diffusive distributed input grating coupling, is presented. The enhancement afforded by additional feedback mechanisms is verified, both with an externally coupled counterpropagating beam and with an integrated optics Bragg reflector.<
