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.
