ABSTRACT:
External cavity, widely tunable lasers and methods of tuning the same are disclosed. One such example laser includes a semiconductor laser, a ring resonator coupled to the semiconductor laser; and a Bragg grating. The Bragg grating is coupled to the ring resonator to reflect a portion of light output by the ring resonator back to the semiconductor laser to select a lasing frequency of the semiconductor laser.
