Abstract
A PIC that includes an InP-based polarization rotator having an improved design that enables at least one of an improved performance and an improved yield of the PIC due to at least one of reduced variations in critical dimensions of the InP-based polarization rotator and reduced overlay errors during fabrication of the InP-based polarization rotator of the PIC. An opto-electronic system including said PIC. A method of fabricating the PIC that includes the InP-based polarization rotator having the improved design.
