  • Publication number: 20200127757
    Abstract: An optical transmitter generates two modulated optical signals by modulating two optical carriers respectively with two binary bit sequences by on-off keying and generates an orthogonal polarization multiplexed optical signal from the two modulated optical signals. The two optical carriers respectively have peak frequency components spaced apart from each other by a predetermined frequency difference and located such that a central frequency of a WDM channel of a WDM grid falls between the peak frequency components. An optical receiver separates the orthogonal polarization multiplexed optical signal into two signals in which components of the two modulated optical signals are combined with different combination ratios, by means of a 1-input, 2-output asymmetric filter whose two optical transmittances intersect at the WDM grid and each have a free spectral range equal to or twice the channel spacing of the WDM grid, and restores the two modulated optical signals from the separated two signals using a DSP.
