Abstract
A tunable laser consisting of a silica-waveguide triple-ring resonator connected directly to a semiconductor optical amplifier is presented. Stable single-mode, grid-hopping free and full-band wavelength-digitally-tuning operations with 50-GHz channel spacing are successfully demonstrated.
