无源波导 meaning in English

passive waveguide

The application of polymers ( as passive waveguide materials ) to intergrated optical sensing ( evanecent wave sensing ) is a new try as compared with that in thermal sensing [ using thermo - optic ( to ) modulators ] or voltage sensing [ using electro - optic ( eo ) modulators ]
相对于温度传感(热光调制器)和电压传感(电光调制器)应用，将聚合物作为无源波导材料用于集成光波导化学传感(倏逝波相位传感)是个新的尝试。
