Abstract :
The paper describes a gain-flattened multiwavelength modelocked semiconductor laser that generates 750 Mb/s return-to-zero pulses into 168 discrete wavelength channels. Optical time division multiplexing multiplies the pulse-repetition rate to 6 Gb/s per channel to yield an aggregate pulse rate of 1 Tb/s. Optical fiber deployment in the access network, which bridges the transport network and subscribers, hinges on the availability of cost-effective wavelength division multiplexing (WDM) light sources. Multiwavelength lasers have evolved into realistic candidates to satiate this need owing to their ability to generate a large number of WDM channels from a single source.
