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.

Abstract: An optical filter includes a first optical channel that includes a first mirror and a second mirror that are configured to reflect one or more ranges of an electromagnetic spectrum, and a first portion of a monolithic spacer that is positioned between the first and second mirrors. A second optical channel includes a third mirror and a fourth mirror that are configured to reflect one or more ranges of the electromagnetic spectrum, and a second portion of the monolithic spacer that is positioned between the third and fourth mirrors. A method of manufacturing the optical filter includes forming a first plurality of mirrors; forming, on the first plurality of mirrors, a monolithic spacer; forming a multilevel etch mask on the monolithic spacer using a grayscale lithography procedure; etching the multilevel etch mask and the monolithic spacer; and forming a second plurality of mirrors on the monolithic spacer.
