Abstract
A temperature compensated laser diode transmitter circuit includes a laser diode, a driver circuit for supplying an a.c. drive current to the laser diode, a thermistor arranged to thermally sense the laser diode, a current source having a first and a second current output controlled by the thermistor, the first current output connected to the driver for temperature compensating the drive current, and the second current output connected to supply a temperature compensated bias current to the laser diode.
