    摘要: An athermalized, polymer overclad integrated optical device (with a multiplexer/demultiplexer or a Mach-Zender interferometer being representative examples) in which thermally-induced shifts in channel wavelengths are minimized. The device includes a doped silica waveguide core on a planar substrate and a polymer overclad having a negative variation in refractive index versus temperature (dn/dT) to inhibit shifts in the channel wavelengths.

    摘要: A passive temperature-compensated integrated optical component having an array of adjacent waveguides, and a slab waveguide located within a groove at an intermediate section of the array. The waveguides have an index of refraction that increases with increasing temperature, and the slab waveguide has an index of refraction that decreases with increasing temperature. The slab waveguide compensates for a temperature-induced change in the refractive index of the waveguides to maintain a generally constant optical path difference between the adjacent waveguides over a temperature range.

    摘要: An athermalized optical waveguide circuit device exhibiting reduced signal power losses includes an optical phased-array comprising a plurality of curved waveguide cores of different lengths supported on a planar substrate, wherein each of the waveguide cores of the array includes a first silica segment, a second silica segment, and a central polymer segment connecting the first silica segment with the second silica segment to form a continuous waveguide core. The device is prepared by forming a plurality of adjacent curved silica waveguide cores on a planar substrate, overcladding the silica waveguide cores with a silica overclad, etching at least one groove into a central portion of the optical phased-array through the overclad and silica waveguide cores, forming a plurality of polymer waveguide core segments connecting a first silica waveguide core segment with a corresponding second silica waveguide core segment to form a continuous waveguide core, and overcladding the polymer waveguide core segments to define a composite optical phased-array comprising a plurality of adjacent composite waveguides. The polymer waveguide core segments have a negative variation of index of refraction as a function of temperature to compensate for the positive variation of the silica waveguide core segments, while providing an uninterrupted waveguide with low power loss of optical signals.
