A Comb-based Colorless Coherent WDM Transmitter
Di Che, Brian Stern, Kwangwoong Kim +4
We propose a comb-based WDM transmitter capable of modulating independent signals to comb lines without demultiplexing them and prove its concept and potential scalability in a WDM…

Frequency Comb-based Wavelength Division Multiplexing and Detection without Wavelength Demultiplexers
Di Che, Zhongdi Peng, Mikael Mazur +1
We demonstrate a wavelength division multiplexing (WDM) concept using demultiplexer-free frequency combs at both transmitter and receiver in a 4-wavelength 200-GHz-grid WDM system…
