Abstract

In this research, we have investigated the sensitivity of an extraordinary optical transmission sensor depending on the angle of incident light. Three types of light, including a collimated beam and focused beams (4× and 10×), were designed for the sensor system. To compare the sensitivity of the sensor, we measured transmittance spectra using deionized water (n=1.333) and refractive-index-matching oils (n=1.360 and 1.380). Those spectra were analyzed in terms of redshifting of the peak, so that we could determine the sensitivity. The sensitivity tended to increase when the collimated beam is used on the system, and we have concluded that the sensitivity could be affected by the incidence angle on an extraordinary optical transmission sensor.

본 논문에서는 특이 광 투과 현상 센서에서 보조 파장 홀 패턴에 입사되는 광원의 각도 조절을 통해 센서의 민감도를 측정 및 분석하여 이를 극대화할 수 있는 방법을 고안하였다. 입사파 광원을 평행화된 광원과 각도가 서로 다른 두 개의 집속화된 광원 총 3개의 광원을 시스템적으로 설계하여 서로 다른 각도로 보조 파장 홀 패턴에 입사되게 제작하였다. 그리고 증류수(n=1.333)와 굴절률 정합액(n=1.360, 1.380)을 사용하여 투과 스펙트럼을 측정하고 센서의 민감도를 계산한 결과 평행화된 광원을 사용하였을 때 센서의 민감도가 향상됨을 확인하였다.
