Simple DQPSK Signal Regenerator Using Electrical Limiting Amplifiers PROJECT TITLE :Simple DQPSK Signal Regenerator Using Electrical Limiting AmplifiersABSTRACT:A easy optoelectronic regenerator for differential quadrature part-shift keying (QPSK) signals is demonstrated. The regenerator consists of two parallel delay interferometers followed by balanced detectors, limiting and driving amplifiers, and a dual-parallel Mach–Zehnder modulator that regenerates noise-suppressed optical QPSK signals. We tend to experimentally show that the regenerator improves the receiver sensitivity by about eight dB at an input optical signal-to-noise ratio (OSNR) of 19 dB at an indication speed of ten Gbaud. Numerical simulation is conducted for higher speed operation at fifty six Gbaud to review the impact of the bandwidth of electrical circuits within the regenerator on the regenerator performance. Electrical power consumption of the regenerator is assessed, and it's shown that the optoelectronic regenerator consumes a similar quantity of electrical power as that consumed by an all-optical version of the regenerator using semiconductor optical amplifiers as a nonlinear part.
