We demonstrate optical wireless transmission with two-dimensional (2D) beam-steering using an optical phased array (OPA). The OPA consists of 64-elements of electro-optic p-i-n phase shifters and thermo-optic tunable n-i-n grating radiators, employed for 2D beam-steering in the transversal and longitudinal directions. The design of the transmitter and receiver device parameters allowed the error-free transmission of 32 Gbps data over a distance of 3 m. The beam-steering range covered 46.0°/10.2° in the transversal/longitudinal direction with a beam divergence of 0.7°/0.9°. When compared with a transmission over fiber, it was confirmed that free-space transmission through the OPA did not degrade the quality of the tens of Gbps signals.

使用硅光相控阵的 32 Gbps 数据传输和 2D 波束控制

我们展示了使用光学相控阵 (OPA) 进行二维 (2D) 波束控制的光学无线传输。OPA 由 64 个电光 pin 移相器和热光可调谐 nin 光栅辐射器组成,用于横向和纵向的 2D 光束控制。发射器和接收器设备参数的设计允许在 3 m 的距离内无差错地传输 32 Gbps 数据。光束控制范围在横向/纵向覆盖 46.0°/10.2°,光束发散角为 0.7°/0.9°。与光纤传输相比,可以确认通过 OPA 的自由空间传输不会降低数十 Gbps 信号的质量。
