Abstract
The temperature dependence of the defect mode in a one-dimensional dielectric photonic crystal heterostructure (PCH) with a superconductor defect was theoretically investigated by simultaneously considering thermal-expansion effect and thermal-optical effect. For comparison, four structures are discussed. It is found that a dielectric PCH with a superconductor defect has very high temperature sensitivity. The average change in the central wavelength of the defect mode is 7.313 nm/K in the range of temperature variation from 10 K to 90 K. The structure may be used as a low temperature sensor.
