| Abstract | Abstract—We demonstrate a tunable filter consisting of a sub-wavelength resonant grating filter cladded by a liquid crystal cell. The resonant wavelength of the grating filter is tuned by electri-cally varying the refractive index of the liquid crystal. A tuning range of around 20 nm has been achieved. Index Terms—Gratings, liquid crystal devices, resonant wave-guide grating filter, tunable filter. I. |
