Abstract: The present invention provides certain CHIP films and coatings, as well as the preparation and uses thereof. Chalcogenide hybrid organic/inorganic polymers or CHIPs may be suitable for use in antireflection coatings for use with infrared optics, for example as applied to lenses for infrared cameras. The coatings may be applied with spin coating and have a thickness related to the quarter wavelength of the desired infrared wavelengths.

Abstract: A photonic device including a first waveguide and a second waveguide is provided. The device includes an interconnect coupled with the first waveguide and the second waveguide. The interconnect includes a substrate. The interconnect includes a film including a refractive index contrast (RIC) polymer and a core. The core includes a first domain having a first refractive index. The core includes a second domain adjacent to the first domain and having a second refractive index. The second refractive index is less than the first refractive index. The core includes a third domain adjacent to the second domain and having a third refractive index. The third refractive index is less than the second refractive index. The second domain is disposed between the first domain and the third domain. The refractive index of the substrate is less than the first refractive index, the second refractive index, and the third refractive index.
