Intensity independent bistable polarization switch based on ordered GaInP

We present a polarization sensitive device showing an adjustable bistable switching behavior. It exhibits switching contrasts of up to 30 dB, electrooptical gains of 40 dB, and an angle hysteresis which can be tuned between 0/spl deg/ and 60/spl deg/. Furthermore, the polarization characteristics are independent of the incident optical power.
