Microphotonic circuits have been proposed for applications ranging from optical switching and routing to optical logic circuits. However many applications require microphotonic circuits to be polarization independent, a requirement that is difficult to achieve with the high index contrast waveguides needed to form microphotonic devices. Chief among these microphotonic circuits is the optical add/drop multiplexer which requires polarization independence to mate to the standard single-mode fiber forming today's optical networks. Herein, we present the results of an effort to circumvent the polarization dependence of a microphotonic add/drop multiplexer with an integrated polarization diversity scheme. Rather than attempt to overcome the polarization dependence of the microphotonic devices in the circuit directly, the arbitrary polarization emanating from the fiber is split into orthogonal components, one of which is rotated to enable a single on-chip polarization. The outputs are passed through identical sets of devices and recombined at the output through the reverse process.
