Abstract:
1. An apparatus comprising: an optical medium; an input splitter coupled to the optical medium; a first delay line coupled to the input splitter such that the input splitter is positioned between the first delay line and the optical medium; a first comb reflector coupled to the first delay line such that the first delay line is positioned between the first comb reflector and the input splitter; a second comb reflector coupled to the input splitter but not the first comb reflector and not the first delay line; a second delay line coupled to the second comb reflector such that the second comb reflector is positioned between the second delay line and the input splitter; an output combiner coupled to the first comb reflector and the second delay line; and an output optical medium coupled to the output combiner such that the output combiner is positioned between the first comb reflector and the output optical medium.
