Paper Abstract
We demonstrate an optical–electrical hybrid equalizer, which comprises an optical domain equalizer fabricated using optical filter banks and an electrical filter in a digital domain by a digital signal processing, to experimentally demodulate degraded 40-Gbaud quadrature phase-shift keying (QPSK) signal. The optical signal-to-noise ratio (OSNR) required for a BER of 1 × 10-3 is improved to 7 dB without an optical equalizer (OEQ) under the back-to-back condition. The fluctuation in the OEQ strength between 0–6 dB will not affect signal quality significantly. The signal degradation caused by the frequency response of devices was minimized using by the hybrid equalizer.
