摘要

我们设计并制造了一种由弯曲波导组成的均匀发射结构的芯片级光学相控阵(OPA)。这种基于绝缘体上硅的器件在整个视场范围内(- 34°~34°)无混叠光束导向，远场可寻址度为6.71°。此外，转向过程呈现平台包线，在−30°~30°范围内强度波动小于0.45 dB。

Dispersion-engineered Optical Phased Array for Aliasing-free Beam-steering with a Plateau Envelope

We design and fabricate a chip-scale optical phased array (OPA) with a uniform emitting structure composed of bent waveguides. This silicon-on-insulator based device demonstrates aliasing-free beam-steering over the entire field-of-view available (−34°~34°), with a far-field addressability of 6.71°. In addition, the steering process exhibits a plateau envelope, with an intensity fluctuation of less than 0.45 dB from −30°~30°.
