US 2023/0146862 A1 · PHOTONIC WAVEGUIDE STRUCTURE

Abstract

A photonic waveguide structure includes at least four photonic waveguide layers disposed in a stack configuration. A first photonic waveguide layer, of the at least four photonic waveguide layers, includes a first active structure associated with one or more particular nonlinear optical characteristics, which include a Kerr coefficient that is greater than or equal to 1×10−18 meters squared per Watt. A second photonic waveguide layer, of the at least four photonic waveguide layers, includes a second active structure associated with one or more particular linear optical characteristics, which include a propagation loss parameter that is less than or equal to 0.5 decibels per centimeter. The first active structure and the second active structure are formed using one or more sputtering processes, and the first active structure and the second active structure are each configured to transmit light with wavelengths from 350 nanometers (nm) to 5000 nm.
