摘　　要：在考虑材料吸收的情况下利用传输矩阵的方法研究光子晶体介观压光效应。研究表明:当在光子晶体的轴向方向施加应力产生应变时,光子晶体缺陷模将向左(波长小的方向)移动;缺陷模透射峰的峰值和半高宽不随应变的变化而变化;当消光系数和有效弹光系数增大时,介观压光系数的绝对值将会减小,即缺陷模透射率对应力的变化越来越不敏感。这为高灵敏应力传感器的设计提供了理论参考。The mesoscopic piezo-photonic effect were studied by transfer matrix method in the case of considering absorption. The results show that when a stress is applied to the axial direction of the photonic crystal which generates strain, photonic crystal defect mode will move to the left （small wavelength direction）. The peak of the defect mode and the width at half maximum of defect mode are constant with the change of strain. With the extinction coefficient and the elasto-optical coefficient increasing, the coefficient of mesoscopic piezo-photonic is getting smaller and smaller. This provides a theoretical for stress sensor designing.
