摘要： 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.

摘要： There is provided a reconfigurable optical modulator comprising a light source and a splitter operative to receive an input signal from the light source and to split the input signal into a plurality of split signals. The optical modulator comprises a plurality of optical amplifiers, each being operative to receive one of the plurality of split signals as an input and to act as a switch having a first state where the split signal is blocked and a second state where the split signal is amplified. The optical modulator comprises a plurality of modulators, each being operative to receive an amplified split signal from one of the plurality of optical amplifiers and to modulate the amplified split signal into a modulated signal. The optical modulator comprises an optical combiner operative to combine a plurality of modulated signals produced by the plurality of modulators to thereby produce a modulated output signal.
