Damascene-Patterned Optical Anisotropy In Integrated Photonics

Abstract

We propose, simulate and experimentally demonstrate a method for realizing spatially-mapped birefringence onto integrated photonic devices and circuits. The fabrication method is based on applying a damascene-like process to dielectric film stacks to form anisotropic optical waveguides. An integrated polarizing beam-splitter (PBS) is realized with unprecedented performance: a record 0.52 octaves of fractional bandwidth (116 THz), maximum on-chip insertion loss of 1.4 ± 0.8 dB, and a minimum extinction ratio of 16 ± 3 dB, pushing it into the realm of wideband spectroscopy and imaging applications. Additionally, photonic structures such as polarization-selective beam-taps and polarization-selective microring resonators are demonstrated.
