摘要: A redundant package for optical components includes an inner package enclosing the optical component, and an outer package enclosing the inner package. A heater may be disposed in the inner package proximate the optical component to control its temperature, and to maintain this temperature control, the outer package creates an isolated air pocket around the inner package which thermally insulates the inner package from the outside environment. The outer package is formed of a material having low thermal conductivity, to promote this insulating function. This package is especially useful if the optical component comprises a planar lightwave circuit (PLC), e.g., an arrayed waveguide grating (AWG), which requires tight temperature control and structural integrity to maintain the integrity of the optical paths.

摘要: A planar lightwave circuit includes an arrayed waveguide grating (AWG), with input and output waveguides, partially curved array waveguides with respective length differences, and planar waveguide regions for focusing optical energy between the input/output and array waveguides. Optimal waveguide widths and spacing along the planar waveguide region facets are disclosed, which are largely determinative of AWG size and optical performance. Also disclosed are optimal cross-sectional waveguide dimensions (e.g., width and height); modified index of refraction difference between the waveguide core and cladding regions; and optimal array waveguide lengths, path length differences, and free spectral range. These features, especially when combined with advanced fiber attachment, passivation and packaging techniques, result in high-yield, high-performance AWGs (both gaussian and flattop versions).

摘要: An optical packaging arrangement combines a planar lightwave circuit (PLC) having an array of waveguides thereon, an array of photodetectors on a substrate to receive light beams coupled out of the PLC by the output ports, and a collimating faceplate, having a plurality of glass cores, extending between the PLC and the photodetector array for coupling the output light beams to respective photodetectors. The faceplate forms a cover for a hermetic cavity encompassing the photodetectors. The PLC is disposed either co-planarly with the faceplate or transversely to it. Light from the PLC is tapped via a plurality of taps formed on the PLC for coupling to the photodetectors.

摘要: An optical component package, in which a transfer molded layer of material (e.g., syntactic foam in one embodiment) is formed at least partially around, or entirely around, the optical component to provide structural and thermal insulation around the component. The optical component may be a planar lightwave circuit (PLC), with a protective passivation layer formed between the PLC and the layer of syntactic foam, to de-couple stresses and thermal transfer between the PLC and the layer of syntactic foam. Strengthening caps, fiber assemblies, and a heater may be provided with the PLC assembly, around which the layer of syntactic foam can also be formed. The protective passivation layer can also be formed between these structures and the syntactic foam; in one embodiment between at least two strengthening caps formed on opposing edges of the PLC. The disclosed package provides numerous structural, thermal and size benefits.

摘要: A scanning optical spectrometer with a detector array is disclosed, in which position of focused spot of light at the input of a dispersive element such as arrayed waveguide grating (AWG) with a slab input, is scanned using a micro-electro-mechanical (MEMS) tiltable micromirror so as to make the dispersed spectrum of light scan over the detector array coupled to the AWG. Sub-spectra recorded using individual detectors are concatenated by a processor unit to obtain the spectrum of input light.
