摘要： A two-dimensional modulator array for modulating a plurality of light beams. The modulator array is comprised of a plurality of stacked wafer layers (401-406). Each of the wafers have a linear array of transversely driven Pockels modulators. The Pockels modulators are formed by placing a plurality of electrodes (407) over a top surface of an optical material. A ground plane resides on the bottom surface of the optical material. Conductive end reflectors (104) are associated with each of the modulator electrodes. These end reflectors reflect light beams back through the wafer. Electrical attachments are connected to the ends of each electrode for controlling the modulation for each electrode. Thereby, separate light beams can be individually modulated.

摘要： A variable spectral resolution agile filter has instantly adjustable spectral resolution with no required mechanical motion and a quickly adjustable center wavelength. Adjustment of the center wavelength is accomplished by reliable piezoelectric actuators (3, 4). Adjustment of the spectral resolution is achieved by changing the finesse of the system, the finesse being governed by the reflectivity of the faces (8, 10). By making one of the faces exhibit electrically variable reflectivity, the finesse of the system is instantly changeable, and thus the spectral resolution is also instantly changeable.

摘要： Methods are disclosed for minimizing laser induced damage to nonlinear crystals, such as KTP crystals, involving various means for electrically grounding the crystals in order to diffuse electrical discharges within the crystals caused by the incident laser beam (13). In certain embodiments, electrically conductive material (31) is deposited onto or into surfaces of the nonlinear crystals (11) and the electrically conductive surfaces (31) are connected to an electrical ground (22). To minimize electrical discharges on crystal surfaces that are not covered by the grounded electrically conductive material (31), a vacuum may be created around the nonlinear crystal.

摘要： A travelling wave optical modulator comprises a Z-cut lithium niobate substrate (4) on which is formed a proton exchanged optical waveguide (10) and a travelling wave electrode (18, 20). The optical waveguide (10) is removed from the electrode (18, 20) intermittently to bring an optical signal in the optical waveguide (10) back into phase with an electric field passing along the electrode (18, 20). The optical signal is delayed relative to the electric field thereby allowing modulation of the optical signal by a non-periodic electric field. The optical waveguide (10) is defined within the boundaries of the top surface of the substrate.

摘要： An electro-optical device (10) is used to alter characteristics of a light beam passing through it. In a particularly preferred embodiment, the device (10) is used as a phase stop having a dynamically variable aperture whose size is defined by the selected application of an electrical potential across one or more concentric, transparent ring-like electrodes (13, 14, 16 and 18). The electro-optical device (10) finds particular utility in a common-path interferometer (40) where fringe visibility is optimized by using suitable servo-electronics (56) to select an appropriate aperture size for the phase stop (10).

摘要： A modulating optical element (10) having ports (1, 2) wherein either port can output or receive light signals. An electrooptic effect is applied to the optical element to allow the light signals to pass or not pass through the optical element. Due to the electrooptic effect in preventing signals from passing through the optic element ("off" state), light signals radiate out (50) of the optical element and are absorbed by the substrate (6) of the optical element assembly. Rather than being lost, the energy from the light signal is converted, via photodetector electrodes (7, 17), to current which may be used for other purposes in the modulator system, such as bias stabilization.

摘要： On a substrate (1) comprised of a lithium niobate single crystal, there is applied an oxygen-inert diffusion barrier, for example in the form of a platinum layer (2), wherein is etched the desired strip pattern structure (6). A titanium layer (7) is then applied, before heating in a diffusion oven in the presence of an oxygen atmosphere. Thus, the titanium diffuses along the strip pattern structure (6) in the substrate wherein it forms an optical channel (8) wherein the light may be retarded and this by the action of an electrical field. The titanium surface is oxidized by heating in the presence of oxygen. The platinum strips (10, 11) remaining along the optical channel (8) form self-adjusting contacts for applying the control voltage.
