    Abstract: A display having polymer dispersed liquid crystals, which display comprises a transparent substrate; a layer comprising polymer-dispersed cholesteric liquid crystal disposed over the substrate, which layer has more than one stable optical state in the absence of an electrical field. The display further comprises a first transparent conductor disposed between the state changing layer and the transparent support, a second conductor on the other side of the state changing layer so that when a field is applied between the first and second conductors, the liquid crystals change state. It has been found advantageous to have a non-conductive, non-field spreading dark layer of sub-micron pigments in a binder for providing an improved light absorbing function, which dark layer is disposed between the layer of polymer-dispersed cholesteric liquid crystal and the second conductor.

    Abstract: An optical wavelength converter, particularly useful in a wavelength-division multiplexing communication system, including a semiconductor junction in one arm of a Mach-Zehnder interferometer through which a data signal at a first wavelength and a probe signal at a second wavelength counter propagate. The junction is reversed biased into avalanche to selectively absorb the data signal and thereby phase modulate the probe signal according to the data impressed on the data signal. The phase modulated probe signal is beat against an unmodulated probe signal, thereby converting the wavelength of the optical carrier. A tunable laser may produce a probe signal of selectable wavelength. The data signal may first be converted by cross-gain modulation to a third wavelength out of band from the other signals before it is interacts with the probe signal.

    Abstract: A cholesteric liquid crystal display device with improved display images is provided. The device includes a transparent front plate (16) with a front conductive film (18) spaced apart from a back conductive film (22) by a gap filled with cholesteric liquid crystal material (24) which can be switched between a transparent state and a reflective state through application of an electric field. The front conductive film (18) is coated with an opaque mask which defines openings (36) for transmitting light. In the reflective state, ambient light entering the device (10) is reflected by the cholesteric liquid crystal (24) through openings (36) in the opaque mask (12) to form a bright image. In the transparent state, ambient light entering the device (10) passes through the cholesteric liquid crystal (24), front film (18) and back film (22) and is substantially absorbed by an underlying opaque layer (14) which is preferably color-matched to the internal mask (12) to form an single color, image-free display area.
