Self-aligned packing of an optical switch array with integrated tapers

An array of 2/spl times/2 switches with integrated tapers has been pigtailed using a silicon submount to self-align both chip and single-mode fibers. Electrical contacts were wirebonded through an opening etched in the submount. We report fiber-to-fiber insertion loss below 10 dB and measurements of wavelength and temperature dependence of the module.<
