Abstract
A loop status monitor for determining the magnitude of the power output of each signal component of a multi-wavelength optical beam includes a dense wavelength division demultiplexing arrayed waveguide and a detector array. The detector elements are butt-coupled to each respective output of the waveguide to reduce insertion loss and cost. The detector array is formed of planar silica material having a plurality of precision ion implanted regions that separate the optical beam into its respective signal components. The signal components are directed to a corresponding detector element of the detector array. Each detector element includes a photodiode that converts the optical beam to an electrical signal indicative of the amplitude of the power of the channel.
