Abstract
A transmission-type polarization insensitive modulator implemented as a polarization insensitive micro ring modulator (PIMRM) includes a first polarization splitter-rotator (PSR) configured to generate a first light beam and a second light beam having a common polarization from an input, a micro ring configured to modulate the first light beam with data to generate a first output signal, and modulate the second light beam with data to generate a second output signal, and a second PSR configured to combine the first output signal and the second output signal to form a modulated output signal, wherein the micro ring is disposed in between the first PSR and the second PSR.
