A Fabrication-Tolerant SOI Polarization Splitter-Rotator with Cascaded MMI Couplers and an Assisted Bi-Level Taper

摘要

We propose a fabrication-tolerant SOI polarization splitter-rotator with cascaded MMI couplers and an assisted bi-level taper. The performance remains very stable even for a large deviation of ±50 nm in terms of device sizes.
