Abstract :
Differential detection of the single modulation sideband of the binary phase-shift-keying (BPSK) signal is demonstrated. Using single-sideband differential detection at the intermediate frequency stage, it is possible to demodulate 2.5 Gbit/s BPSK-modulated optical channels with spacing as narrow as 2.5 GHz. Even though the spectra of the two channels are overlapped, error-free operation is maintained in each channel
