Abstract :
An active control technique which can be used to maintain an external cavity laser transmitter in a single longitudinal mode is described. The circuitry is contained in a single integrated circuit and provides mean power control of the laser output in addition to spectral control. Single-mode operation has been demonstrated over a temperature range of 25°C.
