Abstract
System, devices and methods are described that provide an integrated optical decombiner or optical combiner having both unamplified paths and amplified paths on which power monitoring and control may be located. A preferred multiplexing/demultiplexing optical path through the combiner/decombiner and a corresponding waveguide output/input is identified and optically coupled to a piece of fiber. Temperature control may be provided to tune an arrayed waveguide grating within the combiner/decombiner and minimize wavelength drift therein. Integrated power monitoring may be employed on one or more of the amplified waveguide paths to ensure that a preferred power level or range is maintained on an optical signal.
