PROJECT TITLE :

DQPSK Directly Phase Modulated DFB for Flexible Coherent UDWDM-PONs

ABSTRACT:

A bandwidth-restricted distributed feedback laser directly part modulated with a five-Gb/s differential quadrature phase shift keying (DQPSK) signal is demonstrated in a very statistical ultra-dense wavelength division multiplexing passive optical network. Optical DQPSK modulation was achieved by merely equalizing a four-level waveform. An intradyne receiver primarily based on a a hundred and twenty° optical hybrid with easy differential decoding processing was used to detect and recover the info attaining a sensitivity of −thirty eight dBm at $textrm BER=ten^-3$ . Negligible penalty was observed when adding a second user at five-GHz channel separation.
