Tunable filter based on two cascaded photonic liquid crystal fibers

This paper describes a tunable filter based on two independently tuned photonic crystal fibers (PCFs) filled with the same liquid crystal. Photonic bang-gaps (PBGs) spectral position of both PCF sections can be controlled with two separated temperature controllers. Overall transmission of the device depends on PBGs formed in both liquid crystal infiltrated PCF sections. As a result in such a cascaded device both position and bandwidth of the guided waves can be controlled.
