  • Patent number: 6868199
    Abstract: A fast tunable wavelength selective optical switch is provided to use electro-optic polymer material as the space materials in symmetric Fabry-Perot cavity. In one embodiment, the electro-optic polymer material is an organic-inorganic hybrid material, e.g. alkoxysilane dye (“ASD”)/SiO2—TiO2 hybrid materials in particular design. Part of the selected wavelengths will be transmitted through the Fabry-Perot cavity into one output port of the switch, the left wavelengths will be reflected to another output port of the optical switch. Those selected wavelengths could be tuned because the refractive index of such hybrid polymer material could be changed by the external electrical field at the speed of nanosecond level due to the electro-optic effect response.
