Abstract

Mode-evolution-based polarization rotators in silicon waveguides were studied. The rotator's performance was studied under normal and abnormal launching conditions. The rotator with minimum length of 40μm was demonstrated to provide the polarization rotation with polarization extinction ratio of 15dB at abnormal launching condition. The insertion loss at the transition region was less than 1dB.
