- 論文の詳細を見る
We have recently developed a refractive index (RI) sensor using a band-pass filter composed of dielectric multilayer films deposited on an optical fiber end. The RI is detected as a shift in the wavelength characteristics, and can be read with an optical spectrum analyzer used in this sensor. In this study, we employ a high-speed demodulator, which converts the optical wavelength information into electrical voltage through the slope of the spectral characteristics. A response time of as short as several tens of microseconds is achieved. We also compare the RI sensitivity of the proposed sensor with that of a simple Fresnel-based RI sensor.
