    摘要： An integrated optical waveguide includes a substrate, a waveguide under-cladding layer disposed on the substrate, and a waveguide core, having top and sidewall surfaces, disposed on the under-cladding layer. A glassy surface smoothing layer disposed on the waveguide core top surface and sidewall surfaces and has a refractive index, relative to a refractive index of the waveguide core, that enables guided optical transmission through the waveguide core and the glassy surface smoothing layer. In fabrication of the optical waveguide, a waveguide under-cladding layer is formed on a substrate and a waveguide core having sidewall surfaces and a top surface is formed on the under-cladding layer. A liquid suspension comprising particles of a glassy material is applied on the top and sidewall surfaces of the waveguide core. The applied liquid glassy particle suspension is heated to form a glassy surface smoothing layer on the waveguide core top surface and sidewall surfaces.

    摘要： A novel detection pixel micro-structure allowing the simultaneous and continuous detection of several discrete optical frequencies. A focal plane array comprises a plurality of multi-spectral detection pixels and a connecting platform to electrically connect the pixels. Each of the multi-spectral detection pixels form a resonant optical structure that comprises at least two periodic latticed dielectric reflectors, and at least one optical cavity between the said latticed dielectric reflectors. The latticed dielectric reflectors create a plurality of photonic bandgaps in the spectral response of the pixel. In addition, each optical cavity of the pixel comprises at least two optical resonant modes, corresponding to localized Bloch modes supported by the pixel dielectric structure, wherein each optical resonant mode is localized maximally at, and minimally away from, the optical cavity.
