Abstract :
This letter demonstrates the efficacy of an optical arbitrary waveform generation (OAWG) transmitter in generating high-bandwidth, single-channel optical waveforms with precompensation overcoming chromatic dispersion. Specifically, 20-bit, 200-Gb/s differential phase-shift keying and 40-bit, 400-Gb/s quadrature phase-shift keying packets are precompensated for the 1675.16 ps/nm of dispersion and 4.833 ps/nm2 of dispersion slope present in 100 km of single-mode fiber, and successfully recovered after transmission. The repetitive waveform packets were generated using static OAWG methodology, with a pair of silica arrayed-waveguide gratings through line-by-line pulse shaping.
