Numerical investigations of an ultra-compact polarization beam splitter based on augmented low-index guiding and subwavelength grating structures
We report the design of an ultra-compact polarization beam splitter with high performance that is based on augmented low-index guiding and subwavelength grating (SWG) structures. The transverse-electric (TE) and transverse-magnetic (TM) modes are confined in high-index silicon (Si) and low-index sil...
