  • Temperature compensation for uncooled laser
    Patent number: 6226114
    Abstract: An optical transmitter (200) in a cable television system (100) includes an uncooled laser diode (250) and a thermal compensation circuit (FIG. 2). The thermal compensation circuit includes a voltage controlled attenuator (220) located between the transmitter input (205), at which an electrical information signal is received, and the laser diode (250). The thermal compensation circuit also includes a thermistor (230) that is situated physically near the laser diode (250) and that is characterized by a resistance that varies with temperature. The thermistor (230) is coupled to a controller (225) for sensing thermistor resistance changes, which are indicative of changes in the laser diode temperature, and for selectively controlling the attenuator (220) to attenuate the level of the electrical information signal.
