CMOS兼容的中红外多通道光子晶体传感器
CMOS compatible multichannel mid-infrared photonic crystal sensor
摘要
Abstract
We propose a multichannel two-dimensional optical chemical sensor in a photonic crystal(PhC)slab.The device is composed of four cavities with a center wavelength at 3. 3μm,and the channels are spaced by 10nm. The sensor is designed on an 800-nm-thick silicon-on-insulator platform for standard CMOS technology. The optical characteristics of the nanocavity structure are simulated by 3-D finite difference time-domain(FDTD) method. The transmittance of each channel is about 39%,with non-uniformity of transmittance across channels less than 0. 25dB. The capability of the sensor is demonstrated by detecting carbon tetrachloride and benzene solu-tions,and shows a sensitivity of 209. 2nm/RIU.关键词
