ABSTRACT:
An optical tap is disclosed that may be utilized with bulk optic devices. The optical tap utilizes any pre-existing reflected optical signal that is present in the conventional bulk optic device. The tap includes a beveled fiber stub that is inserted in the path of the reflected optical signal and thus captures this reflected signal, where the bevel is utilized to allow for the reflected signal to be re-directed through the fiber stub. A convention photodetector is coupled to the fiber stub and used to generate an electrical control signal from the captured reflected optical signal.
