Abstract
We demonstrate broadband (1500-1620 nm) and low-loss planar waveguide polarizers with measurement-limited on-chip extinction as high as 75 dB. Polarizers can be fabricated in higher confinement 100-nm-thick as well as lower confinement 40-nm-thick Si 3 N 4 cores to suit a variety of photonic systems.Keywords
