Nonlinear guided-wave grating phenomena

We review a number of nonlinear guided-wave effects using gratings in indium antimonide planar structures. In particular, we report on the experimental demonstrations of guided-wave optical bistability and limiting in an input distributed coupler; butterfly bistability of an input-output grating-coupler combination; all-optical tuning of a distributed feedback reflector; and enhancement of bistability effects by the use of a counter-propagating feedback beam.
