Extended-bandwidth frequency sweeps of a distributed feedback laser using combined injection current and temperature modulation.

Abstract

This article details the generation of an extended-bandwidth frequency sweep using a single, communication grade distributed feedback (DFB) laser. The frequency sweep is generated using a two-step technique. In the first step, injection current modulation is employed as a means of varying the output frequency of a DFB laser over a bandwidth of 99.26 GHz. A… (More)
