Inverse-Designed Photonic Polarization Control for High-Density Integration on Foundry Platforms

Abstract

Compact, wideband structures to enable chip-scale polarization control are essential elements for large-scale integrated photonics. We experimentally validate inverse-designed polarization control structures fabricated on a commercial foundry, demonstrating rotator conversion efficiency of -1.5dB and splitter insertion losses of 1.4dB (TE) and 2.6dB (TM) across C-band.
