InP-based comb generator for optical OFDM
06 March 2011
We propose a new InP-based comb generator for optical OFDM transmission. The device integrates a Mach-Zehnder interferometer inside an amplified ring. We demonstrate a 5-line, 10-GHz-spaced frequency comb with 3-dB spectral flatness which is tunable over 40 nm. © 2011 Optical Society of America
