In this paper, we propose a novel polarization beam splitter (PBS) based on a 3-waveguide directional coupler (DC) with a Si3N4-loaded horizonal slot waveguide as the bridge. The performance of the ...

Split-Beam Spectrophotometers A split beam spectrophotometer contains a beam splitter which channels light along a reference path and a sample path simultaneously to two separate detectors.

Silicon nitride (SiN) has been widely investigated as a promising integration platform for photonic applications. In this paper, we propose an optical power splitter based on SiN with high ...
