Modelocked semiconductor lasers emit short 1 picosecond optical pulses at high pulse repetition frequencies 1 GHz and can be utilized for a wide variety of applications, but are typically geared towards time domain applications, e.g., optical time division multiplexed optical links, optical sampling, etc. Additionally, the periodic nature of optical pulse generation from modelocked semi conductor diode lasers also makes these devices ideal candidates for the generation of high quality optical frequency combs, or multiple wavelengths, in addition to the ultra short temporally stable, high peak intensity optical pulses that one is accustomed to. Modelocked semiconductor lasers are used to generate a set of phase locked optical frequencies on a periodic grid. The periodic and phase coherent nature of the optical frequency combs make it possible for the realization of high performance optical and RF arbitrary waveform synthesis. The resulting optical frequency components can be used for communication applications relying on direct detection, dense WDM, coherent detection WDM, OTDM, and OCDMA. This report highlights recent results in the use of optical frequency combs generated from semiconductors for optical and RF arbitrary waveform generation.
