We describe in more detail a novel InP-based comb generator for optical orthogonal frequency division multiplexed (OFDM) transmission. The device integrates a Mach-Zehnder interferometer inside an amplified ring. In order to maximize the number of lines in the spectrum, the phase modulators were des...
