Abstract
Current regulator circuits using electrical feedback to stabilize the bias currents of semiconductor laser diodes are disclosed. In these electrical feedback circuits laser diode current is sensed with negative-temperature-coefficient resistance to develop voltages which are compared to zero-temperature-coefficient voltages for generating error signals, and these error signals regulate the emission from the laser diode against changes with temperature.
