    • High quality epitaxial layers of monocrystalline materials (26) can be grown overlying monocrystalline substrates (22) such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer (24) comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer (28) of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy and epitaxial growth of single crystal silicon onto single crystal oxide materials. A microresonator device is formed overlying the monocrystalline substrate. Portions or an entirety of the microresonator device can also overly the accommodating buffer layer, or the monocrystalline material layer.

    • A system for dynamically steering a light beam alters the path of a light beam using refraction. The light beam passes through multiple layers of optically transparent elastic material. Electrodes are attached to the bottom and top surfaces of the optically transparent layers. Voltages applied to the electrodes cause the optically transparent layers to deform. This deformation causes a change in the angle at which the light beam intercepts the surfaces of the optically transparent layers. The light beam is refracted based upon the angle of intercept and the index of refraction of the optically transparent layers. The direction of travel of the light beam can thus be controlled by varying the voltages across the electrodes.
    • 用于动态地转向光束的系统利用折射来改变光束的路径。 光束通过多层光学透明的弹性材料。 电极附着在光学透明层的底表面和顶表面上。 施加到电极的电压导致光学透明层变形。 这种变形导致光束截取光学透明层的表面的角度的变化。 基于截取角度和光学透明层的折射率折射光束。 因此,可以通过改变电极两端的电压来控制光束的行进方向。

    • A dual mode optical magnifier system (22) including a plurality of multi-order diffractive optical elements (24) having at least one reflective, refractive and conventional diffractive surface formed thereon, that in combination are operable between a low magnification virtual image display mode (26) and a high magnification virtual image display mode (28). The multi-order diffractive optical elements (24) include a plurality of zones defined by P.times.2.pi., where P is an integer. The use of multi-order diffractive optical elements (24) enables the elements (24) to be very planar and compact in form so as to be incorporated into portable electronic equipment (40 and 60) such as cellular telephones, pagers, smart card readers (20), computers, or the like, while enabling the desired magnification level to be achieved.

    • A phase spatial light modulator composed of a first liquid crystal cell and one or more additional liquid crystal cells. Each of the liquid crystal cells is positioned so that their extraordinary optical axis (N.sub.e) lies orthogonal to the next liquid crystal cell, and the group of cells is positioned along the optical axis of light emitted by an image source. The modulator, or scanner, thereby capable of steering substantially 100% of unpolarized light therethrough. The modulator intended for use within a display system additionally composed of an image source, driver/control circuitry and an optical magnification system. In operation, an external stimulus is applied, such as a voltage supplied by an external power source, thereby spatially changing the phase of light emitted therethrough. The scanning action enhances display resolution of the generated resultant image without an increase in the number of pixels of the image source.
