In this paper the transmission properties in the Uv, visible and infrared (IR) spectra for one-dimensional photonic crystals with different double defects, under the effect of temperature variations has been theoretically studied. Numerical calculations were carried out by using the transfer matrix method (TMM). The multilayer system, air (Si/SiO2)N D1 (Si/SiO2)M D2 (Si/SiO2)L Glass, has been taken as temperature dependent. The numerical results showed that the number of PBG was increased by increasing the degree of temperature variation. In addition, the variation of temperature caused shifting of the photonic pandgaps to higher wavelengths which can be exploited in the design of temperature sensors.
