In a silicon optical wavelength division multiplexing system, multiple optical signals with different wavelengths are combined and transmitted in a single optical fiber through multiplexing technology. The receiving device is responsible for separating each wavelength of optical signal and converting it into an electrical signal for subsequent processing. A silicon optical wavelength division multiplexing optical receiving device is used to convert optical signals into electrical signals, usually using optoelectronic conversion devices such as photodiodes or photodetectors.
