Abstract
Conventional systems use a polarization-maintaining fiber (PMF) in order to maintain the light in the same polarization between a laser light source and an optical waveguide on a photonic integrated circuit (PIC). A polarization controller may be provided at an input port of the PIC configured for the manipulation of one or both of the TEand TMpolarized light modes. The polarization controller may include a polarization beam splitter/rotator (PBSR), including a plurality of phase tuners and a plurality of couplers which are coupled together by waveguides, all of which are integrated in a device layer on the PIC.
