摘要

微型光学光谱仪可用于便携式和可穿戴式应用。这类设备通常基于提供不同光谱响应的光电探测器阵列,或使用复杂的微型色散光学器件。然而,这些方法通常会产生厘米大小的大型系统。在此,我们报告了一种微型光学光谱仪,它基于一个光学间隔集成的光倍增型有机光电探测器,具有可偏置调节的光谱响应。这种方法可以根据一组不同偏置电压下测得的光电流计算重建入射光光谱。该器件占地面积为 0.0004 平方厘米,能够在整个可见光波长范围内宽带工作,分辨率为 5 纳米以下。为了说明这种方法的能力,我们制作了一个 8 × 8 光谱传感器阵列,可用于高光谱成像。

Miniaturized optical spectrometers could be of use in portable and wearable applications. Such devices have typically been based on arrays of photodetectors that provide distinct spectral responses or use complex miniaturized dispersive optics. However, these approaches often result in large centimetre-sized systems. Here we report a microsized optical spectrometer that is based on an optical-spacer-integrated photomultiplication-type organic photodetector with a bias-tunable spectral response. The approach allows the computational reconstruction of an incident light spectrum from photocurrents measured under a set of different bias voltages. The device, which has a footprint of 0.0004 cm2, is capable of broadband operation across the entire visible wavelength with a sub-5-nm resolution. To illustrate the capabilities of this approach, we fabricate an 8 × 8 spectroscopic sensor array that can be used for hyperspectral imaging. Optical-spacer-integrated photomultiplication organic photodetectors with electrically tunable spectral response can provide high-resolution optical characterization across the visible spectrum.
