Abstract :
We have demonstrated an electroabsorption-modulated hybrid integrated wavelength selectable laser source comprised of a spot-size converted 1.55 μm DFB laser array and a spot-size converted semiconductor optical amplifier/EA modulator, mounted on silicon and optically connected via silica-on-silicon waveguides. The InP components are fabricated using a novel dual-waveguide spot-size converter integration technique that produces low coupling losses and uses existing manufacturing techniques. The low chirp performance of this device makes it suitable for long-haul transmission at 2.5 Gbit/s using any of 16 50 GHz spaced channels
