The Research In Application Of The Photonic Crystal Filter

when the photonic crystals was first proposed by Yablonovitch and John in 1987,the structure ,fabrication and Properties of quantum electronic mechanics had got more and more widely researched. The marked Properties of photonic crystals is some wavelength were restrained and band gap was became. Some wavelength is prohibited to transmit in the photonic band gap were finely used to make the good photonic crystal filter.The optical transfer matrix method of film optical was used to research photonic crystals were more widely and finely ,and for this reason ,there are two factor influence the properties of photonic crystals filter:l,how to get more better structure of photonic crystals filter than the existed;2 if there is a better structure ,how to get it's better parameter?This paper will make this two point of the main clue. First, summarize all 1-D structure photonic crystals filter in domestic and external, making a new photonic crystals filter with 1-D polybasic complicated period structure .then, for there many matrix and multiple hump function ,and there is a multi-object optimization of the problem in photonic crystals filter parameter optimization, this paper induce genetic algorithms who can better due to multi-object optimization, and it work good!...
