Chalcogenide hybrid inorganic/organic polymers (CHIPS) for infrared optical materials and devices

A method for establishing optical coupling between spatially separated first and second planar waveguides includes arranging an optical interconnect on the first planar waveguide. The optical interconnect has first and second end portions and an intermediate portion. Each of the end portions has an inverse taper. The second planar waveguide is arranged on the optical interconnect so that the second planar waveguide overlaps with one of the inverse tapered end portions but not the other inverse tapered end portion to thereby enable an adiabatic transition of an optical signal from the first planar waveguide to the second planar waveguide via the optical interconnect. The first and second planar waveguides have different refractive indices at an operating wavelength and the optical interconnect have a higher refractive index at the operating wavelength than the refractive indices of a core of the first planar waveguide and a core of the second planar waveguide.

Chalcogenide hybrid inorganic/organic polymers (CHIPs) for infrared optical materials and devices

An athermal optical waveguide structure such as an optical add drop multiplexer (OADM) or the like is fabricated by a method that includes forming a lower cladding layer on a substrate. A waveguiding core layer is formed on the lower cladding layer. An upper cladding layer is formed on the waveguiding core layer and the lower cladding layer a sol-gel material. The sol-gel material includes an organically modified siloxane and a metal oxide. A thermo-optic coefficient of the sol-gel material is adjusted by curing the sol-gel material for a selected duration of time at a selected temperature such that the thermo-optic coefficient of the sol-gel material compensates for a thermo-optic coefficient of at least the waveguiding core layer such that an effective thermo-optic coefficient of the optical waveguide structure at a specified optical wavelength and over a specified temperature range is reduced.

Probe beams are scanned with respect to waveguide substrates to generate optical harmonics. Detection of the optical harmonic radiation is used to image waveguide cores, claddings, or other structures such as electrodes. The detected optical radiation can also be used to provide estimates of linear electrooptic coefficients, or ratios of linear electrooptic coefficients. In some cases, the poling of polymer waveguide structures is monitored during fabrication based on a second harmonic of the probe beam. In some examples, third harmonic generation is used for imaging of conductive layers.

The present invention relates generally to high sulfur content polymeric materials and composites, methods for making them, and devices using them such as electrochemical cells and optical elements. In one aspect, a polymeric composition comprising a copolymer of sulfur, at a level in the range of at least about 50 wt % of the copolymer, and one or more monomers each selected from the group consisting of ethylenically unsaturated monomers, epoxide monomers, and thiirane monomers, at a level in the range of about 0.1 wt % to about 50 wt % of the copolymer.

A method for obtaining a metal oxide organic compound composite includes dissolving a hydrated yttrium chloride and an epoxide in a solvent, and obtaining a gel including the metal oxide organic compound composite.

A hybrid strip-loaded EO polymer/sol-gel modulator in which the sol-gel core waveguide does not lie below the active EO polymer waveguide increases the higher electric field/optical field overlap factor &#x393; and reduces inter-electrode separation d thereby lowering the modulator's half-wave drive voltage V&#x3c0;, reducing insertion loss and improving extinction. The strip-loaded modulator comprises an EO polymer layer that eliminates optical scattering caused by sidewall roughness due to etching. Light does not encounter rough edges as it transitions to and from the sol-gel and EO polymer waveguides. This reduces insertion loss.
