Abstract
In this paper, a band-pass filter based on photonic crystals is designed by using the principle of frequency domain superposition. The influence of the heterostructure position, period numbers and incidence angles on transmission spectrums are analyzed. The filter can achieve efficient filtering in 240-280â¯nm solar-blind ultraviolet band, with an average transmittance of 72.2%. Simultaneously, a good band-stop appears in near ultraviolet and visible region (300-700â¯nm) and its average transmittance is below 3.4%. It provides a choice in the application of solar-blind ultraviolet detection technology.
