摘要： A polymer-based pellicle structure is disclosed for incorporation into electro-optic modulators used in testing of electronic devices, such as devices incorporated in flat panel displays. The pellicle structure comprises a polymer pellicle base, a dielectric reflector deposited onto the base, the dielectric reflector comprising alternating layers of organic and inorganic dielectric materials. The disclosed pellicle structure provides numerous advantages over the prior art. When the disclosed pellicle structure is terminated with a polymer layer, the propensity for tearing or damage to the pellicle or the tested device is significantly ameliorated, due to the relative softeness, toughness, and much higher elasticity of the polymer over prior art inorganic compounds used for the same application. Other advantages related to production costs, and advantageous properties provided by the polymer layer are also disclosed.

摘要： A reflective display device includes a switching layer, placed between substrates, for switching between a transmissive state for allowing transmission of incident light and a scattering state for scattering the incident light, and a retro-reflector for reflecting an incident ray from the liquid crystal layer so that an outgoing ray of the reflected light is parallel to the incident ray. A pitch of smallest unit structures of the retro-reflector is set to be larger than 0 mm and not more than 5 mm. The retro-reflector is preferably in a form of a corner cube array and has light absorbing surface portions at borders of the smallest unit structures. With this reflective display device, brightness of white state and contrast ratio can be improved.

摘要： The invention provides an electro-optical device, an electronic apparatus using the electro-optical device, and a method for manufacturing an electro-optical device. High-quality image display may be realized by avoiding abnormal exposures during formation of a photosensitive resin layer on a transparent substrate by using photolithography. A TFT-arrayed substrate of a reflective or transflective electro-optical device is manufactured in such a manner that a photosensitive resin is exposed from the front face side of the TFT-arrayed substrate after the photosensitive resin is applied, while the TFT-arrayed substrate is held at the rear face side thereof by a vacuum chuck. In this case, since a light-shielding film is formed at the lower side of a photosensitive resin layer, a risk in that light transmitted through the TFT-arrayed substrate is reflected by the vacuum chuck and thereby transfers marks and the like of suction holes to the photosensitive resin can be reduced or avoided.

摘要： Automatic bias setting circuits for multiple quantum well (MQW) diodes and optical modulators generally are described. Both digital and analog circuits are provided and techniques for utilizing such circuits for monitoring and controlling optical modulator signal quality are disclosed. In one approach, a desired modulation voltage range is determined. A bias voltage is stepped from a first predetermined voltage up to a second predetermined voltage. A maximum differential photocurrent is determined and the bias voltage corresponding to that photocurrent is then employed so that optimal optical modulator signal quality is achieved. An advantageous application of this technique is in wavelength division multiplexed (WDM) systems in which different optical modulators are operating at different wavelengths. In such a system, a different voltage bias will typically be determined for each optical modulator.

摘要： The invention relates to a Kerr type optical modulator and to an all-optical clock recovery circuit operating by active mode locking of a fiber loop laser including such a modulator. Operation is independent of the polarization of the signals presented to the signal input, at wavelength .lambda..sub.s. The wavelength of the clock signal delivered by the clock recovery circuit is .lambda..sub.c. The modulator comprises an even number of segments, and in a preferred embodiment four segments of polarizationmaintaining fiber, with the segments being of equivalent optical lengths, and interconnected by three splices at three locations. At the first and third splices, the neutral propagation axes of the polarization-maintaining fiber are turned through 90.degree.. In an advantageous variant of the invention, a mode converter is inserted in the loop at the second splice, the mode converter comprising an optical demultiplexer and an optical multiplexer together with two polarization-maintaining optical paths interconnecting them. The demultiplexer separates the two different-wavelength optical signals present in the loop of the fiber laser and applies them respectively to said two paths. A splice including 90.degree. rotation of the neutral axes of the polarization-maintaining fibers is made on the path conveying the input signal at wavelength .lambda..sub.s. On the other path, there is no rotation of the axes. The multiplexer then recombines the two signals. The invention is applicable to long distance telecommunications via optical fiber.

摘要： Energy propagating in a dielectric optical waveguide may be transferred from one mode of propagation to another by inducing a spatially undulatory variation in refractive index in the core of the dielectric optical waveguide. Such a variation may be induced by an electro-static field. The electro-static field may be directed either longitudinally of, or transversely of the dielectric optical waveguide. A suitably periodic electro-static field may be generated by positioning a suitable electrode structure about the dielectric optical waveguide. For certain applications it may be desirable to arrange for the spatial period of the electro-static field to vary in a random manner. By arranging for propagating modes to couple to non-propagating modes an optical modulator may be produced.
