Photodynamic therapy instrument is one of the new types of cancer treatment instruments by using photodynamic therapy. In order to solve the color purity problem of photodynamic irradiation treatment, photonic crystal theory was applied and transfer matrix method was used. The bandgap properties of photonic crystals were analyzed by MATLAB programming to select appropriate photonic crystal materials and to determine its structural parameters. The results show that, newly designed photonic crystal structure has good filtering characteristic, which allows only the pass-through of 980nm near infrared light, and has therapeutic effect on liver cancer, gastric cancer and other visceral organ cancers. Photonic crystal filters based on such structure can be applied to ordinary photodynamic therapy instruments and play the greater role in cancer treatment.

Abstract: Photodynamic therapy instrument is one of the new types of cancer treatment instruments by using photodynamic therapy. In order to solve the color purity problem of photodynamic irradiation treatment, photonic crystal theory was applied and transfer matrix method was used. The bandgap properties of photonic crystals were analyzed by MATLAB programming to select appropriate photonic crystal materials and to determine its structural parameters. The results show that, newly designed photonic crystal structure has good filtering characteristic, which allows only the pass-through of 980nm near infrared light, and has therapeutic effect on liver cancer, gastric cancer and other visceral organ cancers. Photonic crystal filters based on such structure can be applied to ordinary photodynamic therapy instruments and play the greater role in cancer treatment.
