摘要： A display 17 comprises a display panel 2 and a backlighting system comprising a light source 3 and waveguide 18. The waveguide 18 comprises a plurality of portions of diffusing material 1Oa to 10f. Light propagates through the waveguide 18 by means of total internal reflection, but may be scattered by a portion 10a to 10f. Scattered light leaving the waveguide 18 through its exit face 15 produces a pattern of light lines for use in illuminating a 3D autostereoscopic image displayed by the display panel 2. Intervening portions 19a to 19f may be provided, formed from a material such as a liquid crystal gel that can be switched between a light transmissive state and a diffusive state. Optical properties of the intervening portions 19a to 19f may be controlled using electric fields. Such a display 17 can be switched between a 2D image mode, in which the intervening portions 19a to 19f are diffusive and the waveguide 18 provides uniform illumination, and a 3D image mode, in which the intervening portions 19a to 19f are transmissive and the waveguide 18 provides illumination in the form of light lines. If the intervening portions 19a to 19f are controlled using passive or active matrix addressing, the waveguide 18 may provide uniform illumination 26 for a first area of the display panel 2 and light lines 27 for a second area of the display panel 2, allowing 2D and 3D images to be displayed simultaneously. The display 38 may further comprise means 40, 41, 42 for detecting the position of a viewer 6 and adjusting the image displayed and the position and/or pitch of light lines accordingly, in order to provide a 3D image that can be seen from the detected viewer position.

摘要： A wavelength selective switch, in which an input optical signal is wavelength-dispersed and polarization-split in two angularly oriented planes. A polarization rotation device, such as a liquid crystal polarization modulator, pixelated along the wavelength dispersive direction such that each pixel operates on a separate wavelength channel, rotates the polarization of the light signal passing through the pixel, according to the control voltage applied to that pixel. The polarization modulated signals are then wavelength-recombined and polarization-recombined by means of similar dispersion and polarization combining components as were used to respectively disperse and split the input signals. The direction of the output signal is determined by whether the polarization of a particular wavelength channel was rotated by the polarization modulator pixel, or not. In this way, a fast, wavelength dependent, optical switch is provided, capable of use in WDM switching applications.

摘要： A gain equalizer in which a multichannel input light signal is split into its separate wavelength components by means of a dispersive element such as a grating, and the spatially separated wavelength components are passed through a linear array of variable optical attenuators based on liquid crystal phase elements which modulate the phase of part of the cross section of the light. Other types of variable attenuators may also be used. The separate attenuated wavelength components are then recombined and output. The attenuation level of each variable optical attenuator is adjusted according to the output of the light as a function of its wavelength components, and in this way, the overall wavelength profile of the output light signal can be adjusted to any predefined form, whether a flattened spectral profile as in gain equalization applications, or a spectral compensating profile or a band blocking profile.

摘要： A fiber optical attenuator utilizing the cut-off phenomenon for single mode propagation of an optical wave down a single mode fiber, comprising an element such as a pixelated liquid crystal element, capable of spatially changing the phase across the cross section of an input optical signal. Such a spatial phase change is equivalent to a change in the mode structure of the propagating wave. The signal propagating in the single mode output fiber is attenuated in accordance with the extent to which higher order modes are mixed into the low order mode originally present. When the mode is completely transformed to higher order modes, the wave is effectively completely blocked from entering the output single-mode fiber, and the attenuation is high. The level of attenuation is determined by the fraction of the wave which is converted to modes other than the lowest order mode, and is thus controllable by the voltage applied to the pixels of the liquid crystal element.

摘要： An optical switch for routing light signals includes a splitter cell and a recombiner cell. Light signals entering the optical switch are initially split into two polarized light signals having different polarizations. The two polarized light signals are then recombined by the recombiner cell and travel towards one of two output ports. The optical switch also includes a polarization changing device that changes the polarization of the two polarized light signals in response to a control signal. The recombined light signal exiting from the recombining cell will proceed in a direction corresponding to one of the two polarized light signals depending on the polarization of the polarized light signals. By applying the control signal to change the polarization of the polarized light signals, the recombined light signal will travel towards one of two output ports. The optical switch can operate with two input ports and two output ports and can switch light signals entering simultaneously from the two input ports, thereby acting as an optical toggle switch. The optical switch is also bi-directional such that the output ports can act an input ports and the input ports can act as output ports. The optical switch is a 2x2 optical switch, but can be combined with other similar optical switches to create larger switches, such as 4x4 optical switches.

摘要： A cylindrical core (10) is surrounded by a tubular cladding (11) composed of a polymer dispersed liquid crystal material. By applying an electric field (E) to the cladding (11), the refractive index of the material can be varied by causing the liquid crystal molecules to re-orient, thereby selectively matching and mis-matching the refractive index of the cladding (11) with that of the core (10). The field (E) is applied generally longitudinally of the cladding (11) by way of electrodes (12 and 13) which are spaced apart in the longitudinal direction of the cladding (11). In an alternative arrangement, the core (10) rather than the cladding (11) is made of polymer-dispersed liquid crystal material, and its refractive index can be selectively matched or mis-matched with that of the cladding.
