摘　　要：对基于体全息技术的WDM器件的衍射效率均匀性进行研究．为获得尽可能均匀的衍射效率,除了考虑传统的光擦除效应外,更进一步考虑到耦合光路几何组态、各信道衍射光波长、衍射角等因素的影响,利用递推法,推导出更加精确的曝光时序．模拟结果表明,利用该曝光时序,各信道可获得均匀的衍射效率．The uniformity of diffraction efficency for demultiplex of WDM based on volume holographic technology is studied. For getting uniform diffraction efficency, the wave, angle and recording geometry are took into account besides light erase effect. And more precise exposure time series is derived with recurrence method. The simulation indicates that all channels can get uniform diffraction efficency with the exposure time series.
