摘要： The present invention is a method and an apparatus for resonant coupling in photonic crystal circuits. In one embodiment, a photonic crystal device comprises a substrate having a plurality of apertures formed therethrough, a photonic crystal circuit (e.g., formed by “removing” a series of apertures), and a strip waveguide extending through the apertures and coupled to the photonic crystal circuit via a surface localized photonic state formed at a surface of the photonic crystal (e.g., in the apertures). The surface localized photonic state facilitates the efficient resonant tunneling of photons from the wavelength-independent strip waveguide to the wavelength-selective photonic crystal circuit, thereby improving the filtering capabilities of the photonic crystal device.

摘要： The present invention is a method an apparatus for forming lateral electrical contacts for photonic crystal based structures. In one embodiment, a photonic crystal structure comprises a substrate having a plurality of apertures formed therethrough, a waveguide formed by “removing” a row of apertures, and a pair of lateral electrical contacts, each spaced a distance away from the waveguide by at least one row of apertures. The optical mode of the waveguide is confined in the lateral direction by the at least one row of apertures. Thus the apertures provide optical isolation for the electrical contacts, which minimizes losses due to absorption of light by the contacts. The contacts may be used to apply voltages for thermo-optic control of the waveguide, for current injection, or for configuring the waveguide as a photodetector, among other applications.

摘要： An optoelectronic circuit fabrication method and integrated circuit apparatus fabricated therewith. Integrated circuits are fabricated with an integral optical coupling transition to efficiently couple optical energy from an optical fiber to an integrated optical waveguide on the integrated circuit. Layers of specific materials are deposited onto a semiconductor circuit to support etching of a trench to receive an optical coupler that performs proper impedance matching between an optical fiber and an on-circuit optical waveguide that extends part way into the transition channel. A silicon based dielectric that includes at least a portion with a refractive index substantially equal to a section of the optical fiber is deposited into the etched trench to create the optical coupler. Silicon based dielectrics with graded indices are also able to be used. Chemical mechanical polishing is used finalize preparation of the optical transition and integrated circuit.

摘要： The present invention is a method and an apparatus for thermo-optic control of optical signals using photonic crystal structures. In one embodiment, a first portion of a split signal is modulated by propagating the signal through a photonic crystal waveguide in which two electrical contacts are laterally spaced from the waveguide region by a plurality of apertures formed through the photonic crystal substrate. A voltage applied across the electrical contacts causes resistive heating of the proximate photonic crystal waveguide through which the signal propagates, thereby modulating the temperature relative to an un-modulated second portion of the split signal that is used as a reference.

摘要： Current may be passed through an n-doped semiconductor region, a recessed metal semiconductor alloy portion, and a p-doped semiconductor region so that the diffusion of majority charge carriers in the doped semiconductor regions transfers heat from or into the semiconductor waveguide through Peltier-Seebeck effect. Further, a temperature control device may be configured to include a metal semiconductor alloy region located in proximity to an optoelectronic device, a first semiconductor region having a p-type doping, and a second semiconductor region having an n-type doping. The temperature of the optoelectronic device may thus be controlled to stabilize the performance of the optoelectronic device.
