    摘要： An electro-optic display comprises a bistable electro-optic medium, a plurality of pixel electrodes, with associated non-linear elements, and a common electrode, disposed on opposed sides of the electro-optic medium. The display has a writing mode, in which at least two different voltages are applied to different pixel electrodes, and a non-writing mode in which the voltages applied to the pixel electrodes are controlled so that any image previously written on the electro-optic medium is substantially maintained. The display is arranged to apply to the common electrode a first voltage when the display is in its writing mode and a second voltage, different from the first voltage, when the display is in its non-writing mode.

    摘要： The invention provides a first process for addressing an electro-optic material having first and second display states differing in at least one optical characteristic and being capable of being changed from its first to its second display state by application of an electric field to the material, the process comprising applying an electrically charged fluid to a portion of at least one surface of the material, thereby changing the display state of a portion of the material. The invention also provides a second process for addressing an electro-optic material, this process comprising contacting the electro-optic material with a non-conductive brush means wet with a conductive liquid while applying a potential difference between the brush means and the electro-optic material.

    摘要： A transistor having a channel width, W, and a channel length, L, defined by non-rectangular electrodes. The transistor is a thin film field effect transistor having an insulated gate electrode. One of a source and drain electrodes is connected to a display electrode and one is connected to a data line. The source and drain electrodes can be interdigitated to provide a desired W/L ratio. The gate is connected to a select line. An overlap region between a display electrode and a select line for another pixel defines a capacitor. The transistor is fabricated to be situated behind the display electrode so as to maximize an aperture ratio. The design enables the use of conventional printing methods, such as screen printing, ink jet printing, printing through a stencil, flexo-gravure printing and offset printing.

    摘要： Embodiments of the invention include an optical system apparatus and method for modulating the strength of a grating such as a long period grating (LPG) within optical systems and devices by varying the light transmission and loss characteristics of the cladding mode, rather than varying the effective refractive index of the fiber layers. According to embodiments of the invention, the use of a light-scattering or light absorptive material in the cladding of the optical fiber or other optical energy transmission medium causes the cladding to switch between a first state that effectively allows coherent coupling of cladding modes and a second state that effectively prevents coherent coupling of cladding modes. The light-scattering materials include electro-optic materials that cause the cladding to switch between the first and second states based on the presence (or absence) of an electric field, magneto-optic materials that cause the cladding to switch between the first and second states based on the presence (or absence) of a magnetic field, and materials capable of phase transitions that cause the cladding to switch between the first and second states based on temperature. The light-absorptive materials include dopants that cause the cladding to switch between the first and second states based on the wavelength of the optical energy. Embodiments of the invention differ from conventional optical media in that, according to embodiments of the invention, the cladding mode loss (attenuation) is varied rather than conventional changes in the index of refraction. The magnitude of the loss according to embodiments of the invention depends on the specification arrangements employed, but such loss typically is defined in dB per unit length in the given cladding mode.

    摘要： In accordance with the invention, an electrically modifiable optical fiber grating device is made by providing a fiber including a grating and forming a plurality of electrically conductive elements along the grating. In response to an electrical signal, the conductive elements modify the grating. In a preferred embodiment, a fiber grating is provided with a plurality of heating elements spaced to selectively heat different portions of the grating. This chirps the spacing between elements of the grating and thereby increases the bandwidth of the device.
