Abstract

An array compatible, fast and high contrast opto-electronic polarization sensitive switch is proposed. The element's electrical configuration is a standard p-i-n heterostructure under reverse bias voltage. Its optical configuration is very similar to an asymmetric Fabry-Perot resonator (AFPR) where an electroabsorptive i-layer is included between the p and n layers, as in a SEED. Both p- and n-layers are Bragg- reflectors. The front mirror of the AFPR is made slightly polarization dependent using a subwavelength grating etched in the top layer of the p-type reflector stack. We calculate the polarization dependent overall absorption and reflection of the device and model the steady state behavior and polarization induced switching properties, for an electroabsorption coefficient that increases linearly with applied voltage. Using a standard load-line analysis we show that changing the input polarization from TE to TM can lead to a dramatic decrease or increase in overall reflectivity.
