“…The PolSK signal is generated based on differential phase-to-polarization conversion in a differential group delay ͑DGD͒ element. 8 A LiNbO 3 phase modulator is used to encoding a continuouswave light at 1546.5 nm with 10-Gb/s differential phase shift keying ͑DPSK͒ format. Then a polarization controller ͑PC͒ is used to adjust the input signal polarization at 45 deg to DGD ͑from General Photonics Corporation, Los Angeles, California͒ principle axes.…”

Abstract.We propose an all-optical wavelength conversion method that can preserve the polarization information of an original signal based on four-wave mixing in a semiconductor optical amplifier. Using this method, we experimentally demonstrate wavelength conversion for a 10-Gb/s polarization shift keying signal with 1.6-dB power penalty at a 10 −9 bit error rate. To our knowledge, it is the first experiment reported on all-optical wavelength conversion for a polarization shift keying format. The converted polarization shift keying signal is successfully transmitted over a 75-km standard single mode fiber with 1.8-dB transmission penalty.

“…1. In our scheme, a PMF is used to convert a DQPSK signal into a polarization shift keying (PolSK) signal [12]. Then, the PolSK signal is converted into two intensity modulation (IM) signals by a polarization beam splitter (PBS).…”

“…Typically, a delay interferometer (DI) [8,9] or equivalent device [10,11] is chosen for demodulating single wavelength DPSK data. Although the use of a DI is much simpler than using a stable local oscillator in a true coherent receiver, it suffers from some significant issues, such as its temperature and polarization sensitivity, which typically require active stabilization.…”

A novel and simple non-return-to-zero differential phase shift keying (NRZ-DPSK) wavelength division multiplexing (WDM) system, which can simultaneously demultiplex and demodulate multiple wavelengths, is proposed and investigated in this paper. The phase-to-intensity demodulation principle is based on detuned filtering, which is achieved by using a single commercial array waveguide grating (AWG) in our scheme. By properly choosing appropriate AWG channels at the transmitter, the AWG at the receiver can act as both the demultiplexer and the demodulator of the DPSK signals. Simulations at 10, 20, and 40 Gbit/s show good flexibility and performance for the proposed system.
