摘要：

A bandwidth-limited distributed feedback laser directly phase modulated with a 5-Gb/s differential quadrature phase shift keying (DQPSK) signal is demonstrated in a statistical ultra-dense wavelength division multiplexing passive optical network. Optical DQPSK modulation was achieved by simply equalizing a four-level waveform. An intradyne receiver based on a 120 degrees optical hybrid with straightforward differential decoding processing was used to detect and recover the data attaining a sensitivity of -38 dBm at BER = 10(-3). Negligible penalty was observed when adding a second user at 5-GHz channel separation.
