ABSTRACT:
A fiber optic tapped delay line is disclosed which has a number of taps simultaneously fabricated in a single length of optical fiber. The light output from each tap is detected by either an electronic photodetector or by an output segment of optical fiber having a lapped surface, the latter technique also being utilizable in the mass production of optical couplers. The device may be used as a transversal filter by summing the outputs from the taps, and the frequency passband may be custom-tailored by selectively weighting the outputs from individual taps.
