摘要： An optical modulator is provided to control the intensity of a transmitted or reflected light. In a transmission mode, a separator splits arbitrarily polarized light into two polarization rays and one is made to travel a separate path from the other. A recombiner causes the two rays to recombine at an output unless an electro-optic phase retarder changes the polarization of the two rays, in which case, both of them miss the output by an amount which is a function of the voltage on the retarder. A normally-off version with low polarization mode dispersion is obtained by changing the orientation of the recombiner. A normally-on version with low polarization mode dispersion is obtained with a passive polarization direction rotation. Similar results can be obtained in a reflection mode where the input and output are on the same side of the modulator. Versions using a GRIN lens are particularly suited to modulation of light out of and back into fiber-optic cables. The device can be operated as a variable optical attenuator, an optical switch, or a high speed modulator and is insensitive to polarization of the input light. A preferred material for the phase retarder is a hot-pressed ceramic lead lanthanum zirconate titanate composition.
摘要翻译：提供光调制器以控制透射或反射光的强度。在透射模式中，分离器将任意偏振光分离成两个偏振光，一个偏振光从另一个行进。重组器会导致两条射线在输出端重新组合，除非电光相位延迟器改变两个射线的极化，在这种情况下，它们都将输出误差减去延迟器上的电压的函数。通过改变重组器的取向，获得具有低偏振模色散的常关型。通过无源偏振方向旋转获得具有低偏振模色散的常导型。在输入和输出位于调制器的同一侧的反射模式下可以获得类似的结果。使用GRIN镜头的版本特别适用于调制光纤到光纤的光纤。该器件可以作为可变光衰减器，光开关或高速调制器操作，并且对输入光的偏振不敏感。用于相缓凝剂的优选材料是热压陶瓷铅锆酸镧锆酸盐组合物。

摘要： A light shutter array element has a plurality of separate electrodes that are formed in parallel and in two or more columns and that are independently served with a predetermined voltage, and a common electrode that so extends as to divide the separate electrodes for each of the columns, that has branch electrode portions extending in a branched manner in a direction to be interposed among the separate electrodes in each of the columns, the separate electrodes and the common electrode being formed on the surface of an electrooptical crystal substrate. The basic feature resides in that the distances are different at a predetermined ratio from the right and left neighboring separate electrodes on both sides of the branching electrode portion of the common electrode to said branching electrode portion. The method of driving the light shutter array element has the basic feature that during the off time of the drive pulse voltage, a short-time pulse voltage is applied to the electrodes in such a manner that the total number of times of the application of said drive pulse voltage and the short-time pulse voltage always becomes constant per a unit time. Further, the PLZT for the light shutter array element is characterized in that the PLZT which forms the sintered product has an average grain size of smaller than 5 νm and has an average grain sectional area of smaller than 1/150 of the area of the dot that is formed.

摘要： A polarization transformer includes at least one plate of transparent polycrystalline material which has an optical axis oriented perpendicular to a propagation direction of incident radiation having a first polarization state. The plate includes electrodes for applying an electric field across a plane of the plate perpendicular to the propagation direction so as to provide controlled phase change such that the polarization of radiation transmitted through the polarization transformer is transformed from the first polarization state to a second polarization state. The plate in a preferred embodiment comprises a ferroelectric complex oxide such as lead lanthanum zirconate titanate (PLZT) material. Such a material provides devices that have very fast response (on the order of microseconds) and low insertion loss.

摘要： A circuit which responds to an input voltage signal for adjusting the voltage applied across electrodes (32A and 32B) of an electro-optic modulator (14). The circuit includes two FETs Q1 and Q2 connected in series. These FETs are operated as voltage controlled variable resistances. The electrodes are connected in parallel across one of these resistances. These resistances vary in response to the input voltage signal to change the voltage applied across the electrodes (32A and 32B). The circuit draws low current while providing sufficient bandwidth for exposing high quality images.
