摘要

我们介绍了基于贴片天线谐振器二维阵列的高速、GaAs-AlGaAs多量子阱光电探测器的开发工作，其价格为10.3\mu \text{m}$。首先，时域有限差分模拟的结果将被提出，允许优化贴片阵列的几何形状和制造第一代探测器与微波共面访问。接下来，我们将报告我们从$dc$光学表征的初步结果，即反射率和光电流测量。

Development of high-speed, patch-antenna intersubband photodetectors at 10.3μm

We present our work on the development of high-speed, GaAs-AlGaAs multi-quantum wells photodetectors at $10.3\mu \text{m}$, based on two-dimensional arrays of patch-antenna resonators. First, the results of FDTD simulations will be presented that allowed to optimize the patch array geometry and fabricate a first generation of detectors with microwave coplanar access. Next, we will report on our initial results from $dc$ optical characterization, namely reflectivity and photocurrent measurements.
