A coherent optical receiver digital signal processing (DSP) scheme is proposed based on spectral clustering, which utilises spectral clustering to cluster the signals outputted by the DSP.
A coherent receiver that can demodulate high-speed in-phase and quadrature signals of light is an essential component for optical communication, interconnects, imaging, and computing.
Here are the primary components of a coherent optical transceiver: Figure 1: Simplified diagram of the building blocks of a coherent QSFP transceiver designed at EFFECT Photonics.
