Avalanche photodiodes (APDs) are critical photodetection devices for high sensitivity and high-speed sensing. Great efforts in bandgap engineering and impact-ionization engineering have been put to achieve high gain-bandwidth products. Plasmonic optical antenna (POA) techniques can change the near-field distributions of the illumination light and thus provide an effective approach to achieve simultaneous enhancement of the gain and the detection speed. We report a metallic circular disk POA array-enhanced APD, where the circular disk POA array was fabricated on top of the p-doped side of the GaAs p-i-n APD. The electric field (E-field) distribution were simulated. The gain and the frequency response of the APD POA-enhanced APD were measured and compared with a reference APD without the POA array. The POA-enhanced APD shows a simultaneous enhancement in the gain and the detection speed.

圆盘等离子体光学天线阵列增强雪崩光电二极管,同时增强增益和检测速度
雪崩光电二极管 (APD) 是高灵敏度和高速传感的关键光电检测设备。在带隙工程和碰撞电离工程方面付出了巨大努力,以实现高增益带宽产品。等离子光学天线(POA)技术可以改变照明光的近场分布,从而提供一种有效的方法来实现增益和检测速度的同时增强。我们报告了一种金属圆盘 POA 阵列增强型 APD,其中圆盘 POA 阵列是在 GaAs 引脚 APD 的 p 掺杂侧的顶部制造的。模拟了电场(E-field)分布。测量了 APD POA 增强型 APD 的增益和频率响应,并与没有 POA 阵列的参考 APD 进行比较。
