Abstract
An optical device and a method of using an optical filter are provided. The optical device includes an optical filter and a narrowband optical source. The optical filter has a refractive index that varies along a length of the optical filter. The narrowband optical source is in optical communication with the optical filter and is configured to generate light having a wavelength at or in the vicinity of at least one of a wavelength corresponding to a local transmission maximum and a wavelength corresponding to a maximum slop of the group index spectrum of the optical filter.
