Laser digital transmitter |
摘要 |
A system for improving performance of lasers in optical digital systems. This is accomplished by superimposing a microwave modulation current on the normal digital signal input. In the case of single mode lasers, this results in essential elimination of modal noise without any eye margin degradation. In the case of multimode lasers, the superimposed signal obviates various nonlinearities in the light output versus current characteristic which can cause eye margin degradation.
