Abstract:
A receiver receiving a phase-modulated optical frequency division multiplexed signal is provided. The receiver includes a light spectrum shaper configured to extract a carrier wave and a modulated light component contained in either one of a short-wavelength-side waveband or a long-wavelength-side waveband with respect to the carrier wave, to output a spectrum-shaped light signal; and an optical-to-electric converter configured to convert the spectrum-shaped light signal into an electric signal.
