| Abstract(in English) | We propose a simple opto-electronic DQPSK signal regenerator. It consists of two parallel branches of delay interferometers with phase delay of π/4 or -π/4 followed by balanced detectors that convert the DQPSK signal into two series of bipolar electrical signals. The electrical signals drive a dual-parallel Mach-Zehnder modulator that generates a noise-suppressed QPSK signal. We obtain stronger noise suppression by using electrical limiting amplifiers after the balanced detectors. We perform signal transmission over a 40km-long fiber after the regenerator, which shows that the regenerated signal exhibits better nonlinear tolerance. |
