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 ...

Optical coherence tomography (OCT) is a widely used optical imaging technology [1]. Current OCT systems contain a variety of fiber and free-space optical components, which add to the instrument size ...
