A polarization beam splitter assisted by a subwavelength grating (SWG) is proposed. The
SWG enables nearly 20-fold beat length reduction for TE, which makes the high extinction …

This Letter presents both numerical and experimental results of a polarization-independent
directional coupler based on slot waveguides with a subwavelength grating. The measured …

Hybrid waveguides consisting of a metal plane separated from a high-index medium by a
low-index spacer have recently attracted a lot of interest. TM and TE modes are guided in …

A compact and high extinction ratio polarization beam splitter using subwavelength grating
(SWG) couplers is proposed and characterized, where the SWG couplers are located …

An ultracompact polarization-insensitive power splitter using silicon-based subwavelength
grating (SWG) is proposed and analyzed, where one input tapered waveguide and two …

A novel polarization beam splitter (PBS) with an extremely small footprint is proposed based
on a multimode interference (MMI) coupler with a silicon hybrid plasmonic waveguide. The …

We introduce a novel polarizing beam splitter that uses the anisotropic spectral reflectivity
(ASR) characteristic of a high-spatial-frequency multilayer binary grating. Such ASR effects …

The polarization beam splitter (PBS) is an essential component in the polarization diversity
circuit to overcome the strong polarization dependence of silicon nanophotonic devices …

We design, fabricate, and test a novel transverse-electric/transverse-magnetic (TE/TM)
polarization beam splitter which is based on the dependence of birefringence on rib width in …

We have stacked subwavelength gratings (SWGs) on a single substrate to create a compact,
integrated circular polarization filter. The SWGs consist of a wire grid polarizer and a …
