Patent number: 7203390Abstract: 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.Type: GrantFiled: August 10, 2005Date of Patent: April 10, 2007Assignee: JDS Uniphase CorporationInventors: Douglas E. Crafts, James F. Farrell, Mark B. Farrelly, Duane Cook, Satyanarayana Rao Peddada

Patent number: 6697553Abstract: 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).Type: GrantFiled: February 15, 2002Date of Patent: February 24, 2004Assignee: JDS Uniphase CorporationInventors: Jyoti Kiron Bhardwaj, Robert James Brainard, David J.

Patent number: 6664511Abstract: A 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 light-wave 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.Type: GrantFiled: October 28, 2002Date of Patent: December 16, 2003Assignee: JDS Uniphase CorporationInventors: Douglas E. Crafts, James F. Farrell, Mark B. Farrelly, Suresh Ramalingam, Kenzo Ishida

Publication number: 20030219192Abstract: Planar lightwave circuits (PLCs) are typically provided with a passivation coating layer to prevent damaging effects of environmental factors. In certain cases, deep trenching or a similar procedure after passivation removes the protective passivation coating, exposing the underlying layers. Without the passivation coating, the exposed core and cladding layers may absorb moisture resulting in an unacceptable shift in their refractive index. A supplemental hermetic sealing technique suitable for use in localized areas of a PLC, e.g., in areas where passivation may have been removed, consists of providing a sealing lid having a sealing surface, and diffusion-bonding the sealing surface of the sealing lid to the bonding surface about the PLC area. Preferably, prior to said diffusion bonding, the upper bonding surface about the PLC area and the sealing surface of the sealing lid are smoothed to facilitate the bonding.Type: ApplicationFiled: May 7, 2003Publication date: November 27, 2003Applicant: JDS UNIPHASE CORPORATIONInventors: Douglas E.
