ABSTRACT:
Passive optical components may be used to tap the optical power, e.g., from fibers of a wavelength switch system. The passive optical components are realized by a standard photonics light-wave circuit (PLC) integrated to the fiber collimator array of the wavelength switch system. The PLC includes multiple waveguide paths that optically couple optical signals from one or more fiber ports to one or more corresponding free space optical component ports. Optical signals traveling through these waveguide paths are tapped by one or more optical taps and coupled to one or more corresponding tap ports. Each optical tap is located such that an optical signal is tapped after it is coupled into one of the waveguide paths.
