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.

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.
