Abstract
Provided herein is a tunable external cavity laser comprising: a gain medium configured to create an optical signal; an external reflector configured to be coupled to the gain medium, and to comprise a Bragg grating; and a phase control section configured to adjust a phase of an entire laser, but to adjust a wavelength of the laser to a longer wavelength than a peak reflectivity of the external reflector.
