Abstract :
Digital dynamic frequency offset removal and DC pilot tone assisted phase noise compensation enables the use of commercially available DS-DBR lasers as both the transmitter and LO in a coherent wavelength switched OFDM transceiver. A 1.5dB penalty relative to low linewidth static lasers is demonstrated under fast wavelength switched operation.
