103-channel chirped-pulse WDM transmitter

Chirped-pulse wavelength-division multiplexing (CPWDM) was recently proposed as a new technique for generating a comb of WDM channels. A key feature of this approach is the possibility to generate and encode data on a very large number of channels using a single short-pulse laser and a single time-division multiplexing modulator. This characteristic makes CPWDM attractive for applications where many channels with moderate bit rates per channels (10-622 Mbit/s) are required. In this paper, we report the generation of 103 independent WDM channels at a bit rate of 37 Mbit/s each from a single CPWDM transmitter. This represents more than a three-fold increase in the number of channels previously reported for this type of source and is, to our knowledge, the largest number of channels reported to date for any WDM transmitter
