65. All-optical switching in a dye-doped liquid crystal Fabry-Perot device, H. Ono and M. Ito, Jpn. J. Appl. Phys. 40 (2001) L206-L208.


We present an all-optical switching device using both large optical nonlinearity of dye-doped liquid crystals and Fabry-Perot cavity. The phase retardation change due to the refractive index change in the dye-doped liquid crystal was converted into the light intensity change using the Fabry-Perot cavity. The optical switching phenomena were explained by theoretically calculating the optical properties of the Fabry-Perot device.
