ABSTRACT:
A semiconductor laser driver comprises a high frequency amplifier. Positive feedback from a load, including a semiconductor laser, is input to the amplifier. This arrangement provides self-sustained oscillation of the circuit at the relaxation oscillation frequency of the semiconductor laser, thus eliminating the need for an external oscillator.
