Abstract
High resolution fast tunable optical filters are described such that each filter includes a tunable single-peak narrow-bandwidth (SPNB) filter and a tunable etalon in tandem with the tunable SPNB filter, where the bandwidth of the tunable SPNB filter is less than the free spectral range (FSR) of the tunable etalon.
Claims26
A high resolution fast tunable optical filter, comprising:
- a tunable single-peak narrow-bandwidth (SPNB) filter;
- and
- a tunable etalon in tandem with said SPNB filter, wherein the bandwidth of said SPNB filter is less than the free spectral range (FSR) of said tunable etalon.
