Abstract
<p>Miniaturized spectrometers are attracting attention because they can perform chemical analysis in a narrow space. One of the most promising methods, spectroscopy using a surface plasmon resonance photodetector has been proposed. However, this method has not been demonstrated on incoherent light condition. Here, we report near-infrared spectroscopy using the photodetector with an incoherent light source whose spectral range is from 360 to 2600 nm. We input incoherent light filtered by a bandpass filter into the photodetector, and we computed incident spectra from the photodetector output. The photodetector output signals have peaks at an incident angle predicted by the theory of surface plasmon resonance. The peak of the computed spectra was shifted by 15 nm from the result obtained from a commercial spectrometer, but their shapes were consistent with each other. From these results, we concluded that spectroscopy using our photodetector can perform on incoherent light conditions.</p>
