Abstract: (473 Views)
Nowadays, two-dimensional materials such as MoS2 have demonstrated distinctive capabilities in optoelectronic applications. In this paper, to achieve high absorption and wavelength adjustability, a defective photonic crystal with three defects is used. the defects are designed as DMD which D and M assumed to be SiO2 and MoS2 layers respectively. Also, defect positions are investigated to find their impact on the absorption, wavelength of defect modes and peak to peak distance. Optimal structure has two defect modes with more than 97% absorption in photonic band gap. The wavelength of defect modes can be tuned by changing the distance between the first and the second defects. Therefor this characteristic is very efficient in designing optoelectronic devices.
