Abstract

We demonstrate for the first time an EA-modulated hybrid integrated wavelength selectable laser comprised of 1.55 /spl mu/m DFB laser array and amplifier/modulator chips fabricated using a novel spot-size converter integration technique, and optically connected via silica-on-silicon waveguides. The device operates at 2.5 Gbit´s over 16 50 GHz spaced channels with SMSR>33 dB, peak power from +1.6 to -6.2 dBm, and r.f. extinction ratio >0.39 dB for 2.6 V/sub p-p/ drive.
