(2010). 107 Gb/s WDM DQPSK systems with 50 GHz channel spacing by low-crosstalk demodulators. Technical Digest - 15th OptoElectronics and Communications Conference, OECC2010 : 300-301. ScholarBank@NUS Repository.9784885522451https://scholarbank.nus.edu.sg/handle/10635/51073We propose a low-crosstalk DQPSK demodulator to reduce the crosstalk in WDM systems. Our results show it can increase the Q-factor by 3-4 dB in a 107-Gb/s/channel system with 50-GHz channel spacing.Conference PaperNOT_IN_WOS
