The transmission spectra of the one-dimensional photonic crystal is researched by the transfer-matrix method,and found that three photonic quantum well structures are constituted in the area of continuous frequency and three resonance transmission peaks of continuous distribution appear in corresponding frequency range,which shows that the palpable quantization effects and the transmission peak’s number of 2n+m or 2m+n and position can be adjusted.Strong localized field appears in the frequency position of transmission peaks,and they are strengthened with the increase of photonic crystal’s thickness in barrier layer.These characteristics have guiding significance to design the polyphyleticly adjusted multi-channel filters which are continuously distributed. 光子晶体量子阱 共振透射谱 局域场 photonic quantum well resonance transmission spectra localized field 10.14188/j.1671-8836.2011.03.002 O734 国家自然科学基金资助项目（50661001）;广西自然科学基金（2011GXNSFA018145,0991026）;广西教育厅科研（201012MS206,201010LX462）;河池学院重点科研课题（2011YAZ-N001,2001YBZ-N001）资助项目 2011-03-01 2021-04-01 3 57
