1. A silicon photonic integrated system in a switch, comprising:
a multi-wavelength laser module, configured to emit n laser beams with different peak wavelengths, wherein n is an integer greater than 2 and laser beams are continuous waves;
a first multiplexer, optically coupled to the multi-wavelength laser module and configured to receive the laser beams and combine the laser beams into a combined beam;
an optical channel having a beam splitter and m light modulators, wherein m is an integer smaller than n, configured to receive the combined beam; and
a light signal generating element, receiving the combined beam through the optical channel and modulating the combined beam to emit a plurality of light output signals,
wherein the beam splitter receives the combined beam through the optical channel, splits the combined beam into a plurality of first beams, and respectively transmits the plurality of first beams to a demultiplexer in the m light modulators, each of the plurality of first beams comprises n laser beams with different peak wavelengths, and the m light modulators respectively modulating the plurality of first beams to respectively emit the plurality of light output signals.
