本文提出并演示了一种由紧凑的锥形阵列组成的平面波发生器，该平面波发生器扩大了光漏波天线光栅波导的孔径，从而获得了较高的天线增益。器件尺寸减小到传统慢锥的一半，而不降低孔径效率。我们证实了硅光子学器件天线增益的完整数值模拟与实测参数估计值之间的良好对应。
This paper proposes and demonstrates a plane-wave generator which consists of a compact taper array and expands the aperture of the grating waveguide (GWG) of optical leaky wave antenna, resulting in a high antenna gain. The device size is reduced to half of a conventional slow taper without degrading the aperture efficiency. We confirm the well correspondence of the antenna gain between the full numerical simulation and the estimation using measured parameters for the device fabricated by silicon photonics.
