Abstract

The integration of air pressure sensing and wireless optical communication is crucial for data acquisition, processing, and transmission in sealed environments, ensuring both vacuum integrity and transmission efficiency while enhancing data security. Herein, this work proposes an optoelectronic integrated sensing and communication (ISAC) system capable of performing air pressure sensing and simultaneously transmitting information via wireless optical signals from a sealed chamber, which is based on an InGaN/GaN multiple quantum well integrated transceiver chip covered with a polydimethylsiloxane porous film. Variations in air pressure are converted into mechanical deformation of the porous film, which modulates the intensity of reflected light and alters the photocurrent detected by the on-chip photodiode, enabling simultaneous pressure sensing and optical signal modulation. The modulated visible light signal is wirelessly transmitted to an external optoelectronic receiver for air pressure data extraction. Experimental results demonstrate that the system can detect air pressure in the range of 51–101 kPa and successfully transmit the corresponding information to an external receiver. The proposed ISAC system features excellent output linearity, rapid response times, and electromagnetic immunity, making it suitable for air pressure detection applications in extreme environments such as vacuum-sealed chambers and underwater conditions.

基于InGaN/GaN MQW的气压无线检测光电集成传感与通信系统

空气压力传感和无线光通信的集成对于密封环境下的数据采集、处理和传输至关重要，可以确保真空完整性和传输效率，同时增强数据安全性。本文提出了一种基于InGaN/GaN多量子阱集成收发器芯片的光电集成传感和通信（ISAC）系统，该系统能够执行气压传感并同时通过密封腔中的无线光信号传输信息，该系统覆盖有聚二甲基硅氧烷多孔膜。空气压力的变化转化为多孔膜的机械变形，从而调节反射光的强度并改变片上光电二极管检测到的光电流，从而实现压力传感和光信号调制。调制的可见光信号被无线传输到外部光电接收器，用于提取气压数据。实验结果表明，该系统可以检测51-101 kPa范围内的气压，并成功地将相应的信息传输到外部接收器。ISAC系统具有出色的输出线性度、快速响应时间和电磁抗扰性，适用于真空密封室和水下条件等极端环境下的气压检测应用。
