Abstract

In this paper, photonic crystal -based filters are proposed. It is different from the narrow band filter with regular channels that Farbry-Perot interference filter and short wave-pass filters are overlapped to the multi-channel photonic crystal filters. The multi-channel photonic crystal filters have two bands in 428nm-449nm of blue light and 535nm- 590nm of green light, the average transmittance is over 90%,which are able to meet the requirements of the projection optics. The brightness and color purity of the system are both improved.
