Abstract
A tunable laser source () with an integrated optical modulator (). The laser source () is a widely tunable semiconductor laser that is comprised of an active region on top of a thick low bandgap, waveguide layer (), wherein both the waveguide layer () and the active region are fabricated between a p-doped region and an n-doped region. An electro-absorption modulator () is integrated into the semiconductor laser (), wherein the electro-absorption modulator () shares the waveguide layer () with the semiconductor laser.
