Analysis of Temperature Sensors Based on Ternary One Dimensional Photonic Crystals with Double Defects

Based on the transfer matrix method (TMM), the interaction of electromagnetic waves in ultraviolet (Uv), visible and Infrared (IR) spectra with ternary one-dimensional photonic crystals with different double defects, has been theoretically studied. The multilayer system has been taken as temperature dependent. The numerical results showed that the number of photonic band gap (PBG) was increased by increasing the degree of temperature. The variation of temperature, the thickness of the second layer and both the type and the thickness of the second defect caused shifting of the photonic ban gaps to higher wavelengths which can be exploited in the design of temperature sensors.
