Abstract
The transmission spectra of one dimensional metallic photonic crystal containing defects are studied using a transfer matrix method. We consider silver as a defect layer with a refractive index dependent on wavelength and temperature simultaneously. Since the loss factor of silver is the function of temperature, we should find a structure that has sharp transmission peaks to model a filter. We present the structure with a coupled defect. It is found that the number of transmission resonant peaks is equal to the number of coupled defects and they are tunable with temperature and incident angle.
