摘　　要：提出一种热光聚合物可变光衰减器 (VOA)的设计分析 ,利用S弯曲的波导提高衰减效率 ,BPM法模拟中验证其衰减动态范围可达 6 0dB ,实现 6 0dB的衰减计算功耗为 6 0mW ,附加弯曲损耗小于 0 .3dB 并且具有很好的极化独立性 ,串扰低 ,尺寸小 。A polymer thermo-optic variable optical attenuator(VOA) is designed and demonstrated for dense waveguide device integration. The device is optimized the compromise between integration capability,integration cost,and attenuation efficiency. With only 60 mW of drive power,optical attenuation of 60 dB has been achieved. The loss of the bent waveguide is less than 0.3 dB. The polymer VOA is attractive in practice due to its compact size,low insertion loss,low cost and low power consumption. In addition,it shows good polarization independence.
