Description

Apolymer containing fine drop lets of nematic LC whose size is smaller than 100 nm is an interesting electro-optic material. We have investigated an electrically tunable optical filter using the polymer as an active cavity in a Fabry-Perot interferometer (FPI). The FPI filter had the free spectrum range of 37 nm in the 1.55-μm range with a band-path of 0.6 nm and the transmission loss of 2.4 dB. The polarization dependent loss was smaller than 0.17 dB. The transmitted peak shifted to lower wavelengths as the applied electric field increased. This resulted in a tuning range of about 10 nm at 300 V. The switching time was about 370 μs.
