An optical waveguide structure comprises a nonlinear optical waveguide comprising a set of segments, a set of extension optical waveguides, and a set of wavelength selective couplers that couples light between set of segments in the nonlinear optical waveguide and the set of extension optical waveguides based on a wavelength of light.

Disclosed herein are methods and apparatuses for curing a polymerizable material capable of cure through a redox reaction by electrically contacting the polymerizable material with an anode and a cathode to create a voltage bias that promotes curing of the polymerizable material.

Electrochemical curing of redox-active sealants and adhesives

A method and mode conversion waveguide system for converting a mode of a light is provided. The light is sent through a single mode waveguide, wherein the light has a first mode while traveling through single mode waveguide. The light is sent from the single mode waveguide into a multimode interference region having connected to the single mode waveguide. The light is reflected with a cavity within the multimode interference region in a manner that causes the light to propagate away from the single mode waveguide. The light is output from multimode interference region, wherein the light has a second mode.

Mode conversion waveguide system

A wavelength selective filter includes a filter material. The filter material includes a host matrix doped with metal ions. The filter material has a transmission region within a deep ultraviolet (UV) range such that UV light at wavelengths within the transmission region is transmitted through the filter material.

Ultraviolet light wavelength selective filter

An optical waveguide structure comprises a nonlinear optical waveguide comprising a nonlinear optical material having a second order nonlinear coefficient that changes with a direction of light propagation. A first portion of the nonlinear optical waveguide in which a light propagating through the first portion is affected by a positive value of a second order nonlinear coefficient. A second portion of the nonlinear optical waveguide in which the light propagating through the first portion is affected by a negative value of a second order nonlinear coefficient, wherein a set of dimensions in the nonlinear optical waveguide in the first portion and the second portion is selected to cause the light to have a phase walk-off that is an odd multiple of 180 degrees.
