Abstract
An edge-emitting laser includes an active gain section and a reflector section optically coupled to the active gain section. The active gain section is configured to amplify an optical power of light across a wavelength range. The reflector section is configured to selectively reflect light of a selected wavelength within the wavelength range. The selected wavelength is tunable via high-frequency index modulation of the reflector section. The active gain section and the reflector section collectively form an optical cavity configured to lase coherent light in the selected wavelength.
