Radiative Properties and Controlling of Coherent Thermal Radiation Source Consisting of Onedimensional Photonic Crystals Containing Negativeindex Materials
The photonic crystals (PCs) with defect layer containing negativeindex materials coated over a SiC substrate are investigated by a transfer matrix method. The results show that this coherent thermal radiation source has very sharp emissivity peaks within a narrow wavelength band at a welldefined direction; the quality factor of the emissivity peak is high. This emissivity peak is not sensitive to the emission angle, polarization, and scaling factor of the photonic crystals in the structure. The value, quality factor, and position of the emissivity peak can be effectively controlled by tuning the thickness and refraction index of the defect layer.
