Wong Photonic Systems Research Laboratory, Department of Electrical and Electronic Engineering, The University of Hong Kong, Hong Kong kywong@eee.hku.hk Abstract: We have experimentally demonstrated a single pump distrib- uted parametric amplification (DPA) system for differential phase shift keying (DPSK) signal in a spool of dispersion-shifted fiber (DSF). The gain spectrum of single pump DPA is thoroughly investigated by both simulation and experiment, and a possible reference for optimal input pump power and fiber length relationship is provided to DPA based applications. Furthermore, DPSK format is compared with on-off keying (OOK) within DPA scheme. Eight WDM signal channels at 10-Gb/s are utilized, and −9 approximately 0.5-dB power penalties at the bit-error rate (BER) of 10 are achieved for return-to-zero DPSK (RZ-DPSK), comparing to larger than 1.5-dB with OOK format. In order to improve the system power efficiency, at the receiver, the pump is recycled by a photovoltaic cell and the converted energy can be used by potential low-power-consuming devices, i.e sensors or small-scale electronic circuits. Additionally, with suitable components, the whole DPA concept could be directly applied to the 1.3-μ m TI - Distributed parametric amplifier for RZ-DPSK signal transmission system JF - Optics Express DO - 10.1364/oe.20.019271 DA - 2012-08-08 UR - https://www.deepdyve.com/lp/unpaywall/distributed-parametric-amplifier-for-rz-dpsk-signal-transmission-ehW0jafEAA DP - DeepDyve ER -
