Omnidirectional photonic crystal reflector used in ultraviolet region

According to the incident angle domain, the design of an ultraviolet omnidirectional reflector deposited on substrate of quartz glass is briefly presented. The spectral wavelength region of the design is from 328.95nm to 352.11nm and the relative bandwidth is 6.80% in theory. An experiment has been done to verify the design by using HfO2 and SiO2. The experimental result shows that the band gap corresponds to wavelength band from 331.2nm to 350.4nm and the relative bandwidth is 5.63%.
