Abstract:
An optical apparatus comprising:an optical splitter/combiner device which includes at least one input channel which receives optical signals into the optical apparatus, and at least one output;a tap for diverting some portion of the optical signals propagating from an output of the splitter/combiner;a detecting device which includes a wavelength selective device having at least one channel which receives the tapped or diverted signal portion(s) from the splitter/combiner, and at least one output;a detector connected to at least one output of the detecting device for evaluating at least one selected characteristic of an optical signal on a predetermined channel;a feedback link between the detector and a control mechanism which is capable of controllably affecting the selected characteristic of at least one of the optical signals received into the optical apparatus; anda feedback link between the detector and a control mechanism which is capable of controllably affecting passbands of a plurality of channels of the splitter/combiner device.
