Abstract:

This thesis presents the design, implementation and evaluation of a depowered, stabilized-output laser diode drive unit for use in an analog fiber- optic communication transmitter. The driver circuits provide for a stable temperature-controlled operating environment by monitoring the thermistor in the laser diode module and by controlling the current to the modules integral thermoelectric cooler. Output optical power is maintained at desired bias and peak-to-peak levels by processing the signal from the monitor photodiode and amplifying if necessary the ac and dc drive units. These efforts offset the degradation of the laser diodes capabilities due to heat and age.
