摘　　要：用传输矩阵法研究对称结构一维光量子阱(AB)m(ABCBA)n(BA)m的光传输特性,结果发现:随n的增加,光量子阱(AB)5(ABCBA)n(BA)5的透射谱出现(2n-1)条共振透射峰,量子化效应明显;量子阱内部出现很强的局域电场:当n=1时,光量子阱(AB)m(AB-CBA)1(BA)m内部局域电场强度随着m增加而增强,而当m=5时,光量子阱(AB)5(AB-CBA)n(BA)5内部局域电场强度不随n的变化而改变,但局域范围扩大。这些光学传输特性,为光子晶体设计新型光学器件提供指导。Using the transfer matrix method,the transmission properties of one-dimension photonic quantum well（AB）m（ABCBA）n（BA）m with mirror symmetric structure is studied.Results show that with the increase of n,（2n-1）resonance transmission peaks appear in the transmission spectra of photonic quantum well（AB）5（ABCBA）n（BA）5,and quantization effect is obvious.Strong electric field appear in the internal field quantum well.When n=1,the intensity of internal electric field of light quantum-well（AB）m（ABCBA）1（BA）m increases with m,while m=5,intensity of internal electric field light quantum well（AB）5（ABCBA）n（BA）5 don′t change with the change of n,but local area expands.These optical transmission properties provide guidance for the design of new optical device of photonic crystal.
