我们首次详细研究了集成在法布里-佩́ROT腔中的光学漏波天线的辐射性能。结果表明，辐射方向图可以表示为在谐振器中反向传播的两个漏波的干涉产生的辐射方向图，从而给出了实现优化的宽边辐射，即垂直于波导轴的设计方法。因此，我们报告了一种可实现的由半导体和介质区组成的OLWA。理论建模得到了全波仿真结果的支持，得到了较好的一致性。我们的目标是通过在半导体区产生过量载流子来控制宽边方向的辐射强度。例如，我们表明，谐振器的存在可以提供一种有效的方式来增强辐射水平调制，其值高达13.5分贝，为具有新颖的有前途的辐射控制能力铺平了道路，这可能允许产生非常快的光开关。
We provide for the first time the detailed study of the radiation performance of an optical leaky wave antenna (OLWA) integrated into a Fabry-Pérot resonator. We show that the radiation pattern can be expressed as the one generated by the interference of two leaky waves counter-propagating in the resonator leading to a design procedure for achieving optimized broadside radiation, i.e., normal to the waveguide axis. We thus report a realizable implementation of the OLWA made of semiconductor and dielectric regions. The theoretical modeling is supported by full-wave simulation results, which are found to be in good agreement. We aim to control the radiation intensity in the broadside direction via excess carrier generation in the semiconductor regions. We show that the presence of the resonator can provide an effective way of enhancing the radiation level modulation, which reaches values as high as 13.5 dB, paving the way for novel promising radiation control capabilities that might allow the generation of very fast optical switches, as an example.
