Abstract

The teachings herein provide a method and apparatus for interconnecting photonic devices using an advantageous technique that forms an end-to-end optical path between photonic circuits using photonic wire bonds and a bridging glass member. The photonic wire bonds couple the photonic circuits to respective ends of an optical waveguide formed in the glass member. The end-to-end optical path thus comprises a “composite” optical waveguide that includes the photonic wire bonds and the optical wave-guide. Advantageously, these composite optical waveguides are formed in-place according to a process whereby the various components are placed into at least a rough alignment on a substrate and, after deposition of polymer photoresist, a femtosecond laser beam traces the end-to-end optical path, thereby forming the respective photonic wire bonds and optical waveguide in place.
