Abstract
A laser comprising a laser cavity formed by a first optical reflector, a gain region, a second optical reflector having a plurality of reflection peaks, and at least one optically active region. The first mirror may be a DBR or comb mirror and the second mirror may be a comb mirror. The spectral reflectance of the second optical reflector is adjusted at least partially based on an electric signal received form the optically active region such that only one reflection peak is aligned with a cavity mode formed by the first and second reflector.

A laser comprising:
- at least one gain region including a gain configured to generate light;
- a first optical reflector at one end of the gain region, the first optical reflector having at least one reflectance peak in a gain bandwidth of said at least one gain region;
- a second optical reflector having a plurality of reflection peaks at another end of the gain region, the first optical reflector and the second optical reflector forming a cavity including said at least one gain region therein, the cavity having a plurality of cavity modes spaced apart from each other;
- electronics configured to adjust the temperature of at least said second optical reflector;
- and
- at least one waveguide region extended in a longitudinal direction between said at least one gain region and the second optical reflector such that the second optical reflector is thermally isolated from the at least one gain region.
