초록
For the purpose of carbon-dioxide (CO2) sensors,we propose a photonic crystal (PhC)-type filter that has a narow pas band at a wavelength of 4.26 μm in the infrared region. Using the nite- difference time-domain (FDTD) method, we obtained the transmision spectra for various shapes and sizes of the air holes in the PhC type filters. On the basis of the numerical results, we designed and fabricated a PhC-type filter. By measuring the transmision spectra of the fabricated devices, we confirmed that the PhC-type filter could be a candidate for an element of an optical gas sensor. The behavior of the spectral response of the filter with respect to the shape and the size of the air holes was also analyzed.
