ABSTRACT:
A method and circuit for generating controlled light signals from electronic data signals in a semi-conductor laser transmitter of the type having a stimulated emission cavity with at least two electrical input contacts determining corresponding separate cavity regions. Electronic data input signals are applied to each input contact to drive the associated cavity region above a stimulated emission threshold level to generate cross-coupled stimulated emission by interaction of each region with carriers of the other region or regions. The electronic data signals are varied to control optic intensity and frequency according to pre-defined characteristics of the cross-coupled stimulated emission.
