Abstract
A silicon photonics module may include a waveguide for receiving and transmitting an optical beam. The silicon photonics module may include a tap connected to the waveguide to allow measurement of an optical power of the optical beam. The silicon photonics module may include one or more splitters connected to the waveguide to tap a portion of the optical beam from the waveguide and to split the portion of the optical beam into a first part and a second part. The silicon photonics module may include a first Mach-Zehnder interferometer (MZI) to filter the first part to allow measurement of an optical power of the filtered first part. The silicon photonics module may include a second MZI to filter the second part to allow measurement of an optical power of the filtered second part.
