FULL BAND PASS OPTICAL FILTER AND METHOD FOR REDUCING DISPERSION OF OPTICAL PULSE

摘要

PROBLEM TO BE SOLVED: To provide the full band pass optical filter that reduces dispersion of transmitted optical pulses. SOLUTION: This full band pass optical filter reduces dispersion of optical pulses 120 that are transmitted through the filter. The filter applies a desired phase response to the optical pulses that are transmitted through the filter to reduce the dispersion of the optical pulses. The filter has also a frequency independent amplitude response and has a structure that includes at least one feedback path 145, a splitter/combiner 143, an input port and an output port.
