Abstract :
Results for a simple, exact frequency synthesizer for dense wavelength-division multiplexing (WDM) are reported. Channel selection over >1-THz range with programmable channel spacing up to 25 GHz and absolute optical frequency referencing is achieved using widely tunable sampled grating distributed Bragg reflector (DBR) lasers, injection-locked to an amplified fiber loop comb generator.
