摘要

采用硅玻璃平面波导耦合器和单模光纤的精密长度，设计并制作了光纤罗特曼透镜原型。形状因子光子波束形成器与宽带线性天线阵列集成，提供8个波束指向方向，分别为/spl plusmn/7.5/spl deg/、/spl plusmn/22.5/spl deg/、/spl plusmn/37.5/spl deg/和/spl plusmn/52.5/spl deg/。在2.0至4.0 GHz频段内，记录所有波束的频率增量为500 MHz的方位天线方向图，以演示无斜视性能。

Eight beam prototype fiber optic Rotman lens

A prototype fiber optic Rotman lens was designed and fabricated using silica glass planar waveguide couplers, and precision lengths of single mode optical fiber. The form-factored photonic beamformer was integrated with a wideband linear antenna array to provide eight beam pointing directions corresponding to /spl plusmn/7.5/spl deg/, /spl plusmn/22.5/spl deg/, /spl plusmn/37.5/spl deg/, and /spl plusmn/52.5/spl deg/. Azimuthal antenna patterns were recorded for all beams at frequency increments of 500 MHz over the 2.0 to 4.0 GHz band to demonstrate squint free performance.
