On-chip optical wireless links are attracting a great deal of interest as they can provide a possible solution to overcome the drawbacks associated with wired connections. In this paper, we propose a new approach for on-chip communication using optical wireless switches based on thin-film lithium niobate on insulator (LNOI) technology. The optical wireless switches exploit reconfigurable optical phased arrays (OPAs) both at the transmitter and at the receivers. We investigate the radiation characteristics and design criteria of the LN antenna element serving as a unit radiator in the OPAs. We then demonstrate the implementation of an on-chip optical wireless switch in a simple infinite homogeneous host medium and assuming a realistic multilayer structure configuration. Moreover, we examine the impact of various geometrical parameters and the fabrication imperfections on the device performance and provide a discussion on the design optimization. Our findings assess the feasibility of optical wireless switches based on LNOI technology for on-chip wireless communication.

基于光学相控阵片上通信的 LNOI 无线开关


片上光学无线链路引起了极大的兴趣，因为它们可以提供一种可能的解决方案来克服与有线连接相关的缺点。在本文中，我们提出了一种使用基于绝缘体上薄膜铌酸锂（LNOI）技术的光学无线开关进行片上通信的新方法。光学无线开关在发射器和接收器处均采用可重构光学相控阵 (OPA)。我们研究了作为 OPA 中的单元辐射器的 LN 天线元件的辐射特性和设计标准。然后，我们演示了片上光学无线开关在简单的无限同质主机介质中的实现，并假设了现实的多层结构配置。此外，我们还研究了各种几何参数和制造缺陷对器件性能的影响，并对设计优化进行了讨论。我们的研究结果评估了基于 LNOI 技术的光学无线开关用于片上无线通信的可行性。
