Abstract: There may be provided a silicon photonics unit that may include an input waveguide that is configured to convey an input optical signal; a distribution unit (DU) that comprises a DU input port, a first DU output port, a second DU output port and a distribution core; wherein the distribution core is configured to receive the input optical signal, split the input optical signal to a first optical signal and a second optical signal, provide the first optical signal to the first DU output port and provide the second optical signal to the second DU output port; a photodetector (PD) that comprises a PD's first optical input port, a PD's second optical input port, and a PD's electrical output port; wherein the PD is configured to output, via the PD output port, a PD output signal indicative of the first optical signal and the second optical signal; a first optical path that comprises a first waveguide and is configured to convey the first optical signal to the PD's first optical input port; and a second optical path that comprises a second waveguide and is configured to convey the second optical signal to the PD's second optical input port.
