A planar optical waveguide is provided. The planar optical waveguide includes a polymer substrate having a coefficient of thermal expansion, a first cladding disposed on the substrate, and a core disposed on at least a portion of the first cladding. The core is a halogenated polymer having an absorptive optical loss of less than approximately 2.5&#xd7;10dB/cm in the range from about 1250 to 1700 nm. The core has a thermo-optic coefficient and a refractive index, a product of the thermo-optic coefficient and the reciprocal of the refractive index being approximately equal to the negative of the coefficient of thermal expansion.

An optical waveguide is provided. The optical waveguide includes a polymer substrate and a lower cladding disposed on the substrate. The lower cladding is a first perhalogenated polymer. The optical waveguide also includes a core disposed on at least a portion of the lower cladding. A method of manufacturing the optical waveguide is also provided.

Polymer optical waveguides on polymer substrates

A microresonator is provided that incorporates a composite material comprising a polymer matrix and nanoparticles dispersed therein. The microresonator includes the composite material having a shape that is bounded at least in part by a reflecting surface. The shape of the microresonator allows a discrete electromagnetic frequency to set up a standing wave mode. Advantageously, the polymer matrix comprises at least one halogenated polymer and the dispersed nanoparticles comprise an outer coating layer, which may also comprise a halogenated polymer. Methods for making composite materials and microresonators are also provided. Applications include, for example, active and passive switches, add/drop filters, modulators, isolators, and integrated optical switch array circuits.

Nanocomposite microresonators

An optical waveguide assembly is disclosed. The optical waveguide assembly includes having a substrate face, a cladding disposed on the substrate, and a waveguide core disposed within the cladding. The waveguide core has a waveguide core face such that the waveguide core face is aligned with the substrate face. The assembly further comprises a fiber support assembly having a support face in contact with the substrate face and a fiber having a fiber core face optically aligned with the waveguide core face. Non-adhesive means fixedly connects the substrate face to the support face. A method of non-adhesively bonding an optical waveguide to a fiber support is also disclosed.

Adhesive-free bonding method of fiber attachment for polymer optical waveguide on polymer substrate

In accordance with the invention, the present invention provides for a polymer comprised of a general composition. The polymer has a first rare earth element, a second rare earth element, one of the elements of Group VI , one of the elements of Group V , a first fully halogenated organic group, a second fully halogenated organic group. A method of manufacturing the polymer is also disclosed.

Codopant polymers for efficient optical amplification

Disclosed are cost-effective, compact, optically pumped, high gain, rare earth polymer materials such as, erbium (Er,) perfluoro polymers, optical fibers made from the materials and waveguide amplifiers made from the materials having low-loss at telecommunications wavelengths for operation in communications network systems. The polymer amplifier is based on the use of novel high performance rare earth (RE) polymer materials. The new discovered highly transparent RE polymer materials are directly synthesized at high RE ion concentrations (&tilde;10,10,rare earth ion/cm,&tilde;10% wt) with each metal ion encapsulated and physically buffered by insulating, covalently bonded, perfluorinated phosphate ligands that then form the high temperature stable, polymer backbone matrix. This is distinctly different from widely studied inorganic glasses and single crystals where RE ion salts are doped directly into the host but only to relatively low levels (<0.1% wt).

Rare earth polymers, optical amplifiers and optical fibers

A multimode optical fiber includes an inner core and an outer core on the inner core having different refractive index profiles. The refractive index profile of the outer core is graded, while the refractive index profile of the inner core may be graded. The refractive index profiles have the same value at the inner core--outer core boundary.
