摘要： A power efficient assembly is provided for applying a temperature gradient to a Fiber Bragg grating. The assembly includes inner and outer enclosures, the outer enclosure defining an insulation chamber around the inner enclosure. The respective ends of the inner and outer enclosures are in thermal contact. A heat exchange system, such as coiled resistive wires or thermo-electric coolers, applies different temperatures to the opposite ends of the outer enclosure.

摘要： An optical coupling assembly for coupling light from an optical fiber including an angled tip into a planar waveguide via a waveguide coupling element is provided. In one embodiment, the optical fiber extends along the planar waveguide with the angled tip positioned such that light propagating in the optical fiber is coupled by the waveguide coupling element to propagate in the planar waveguide in counter propagation with respect to a fiber propagation direction. In another embodiment, the optical fiber includes a tapered peripheral portion tapering toward the angled tip and is disposed over the planar waveguide with the tapered peripheral portion extending therealong such that light propagating in the optical fiber is coupled to propagate in the planar waveguide with either forward or counter propagation. Embodiments of the present invention may be part of various photonic integrated circuits and may be manufactured more easily than known optical coupling assemblies.

摘要： An optical system may include a substrate that includes an etched region and a laser-induced breakage region. The optical system may further include an optical waveguide disposed on the substrate. The optical system may further include an optical device coupled to the optical waveguide within the etched region. The laser-induced breakage region may produce a predetermined coupling gap between the optical waveguide and the optical device.

摘要： An integrated silicon-based photo-detection system, fabricated in an integrated silicon based structure on a silicon-on-insulator (SOI) wafer, includes a photodiode fabricated on an isolated area surrounded by a light barrier, where the light barrier is an area where the SOI wafer is removed, an optical waveguide that guides an input signal light into the photodiode, and external electrical traces that the free electron carriers flow into as photocurrent. A method of fabricating an integrated silicon-based photo-detection system in an integrated silicon based structure on a silicon-on-insulator (SOI) wafer, includes performing deep etching to create a light barrier surrounding an isolated area on the SOI wafer, fabricating a photodiode in the isolated area surrounded by the light barrier, fabricating an optical waveguide that guides an input signal light into the photodiode, and wirebonding external electrical traces to connect to the remainder of the integrated silicon based structure.
