摘要：
A method of calibrating a tunable laser having a distributed Bragg reflector includes, aligning a reflection peak of the distributed Bragg reflector with a target cavity mode of a plurality of cavity modes defined by a total optical path length inside a resonant cavity of the tunable laser. The method includes aligning a resultant lasing mode with a target wavelength of an output wavelength grid. The resultant lasing mode is formed by alignment of the reflection peak of the distributed Bragg reflector with the target cavity mode. The method also includes setting a target output power and a target extinction ratio of the tunable laser.
