Abstract
A Littrow-configured grating-coupled external cavity wavelength tunable laser monolithically integrated with a semiconductor optical amplifier, an etched grating, and a beam steering controller (BSC) is demonstrated. Using incidence angle variation induced by current injection into the BSC region, 7 nm of wavelength tuning range and over 35 dB side-mode suppression ratio is obtained.
