提出了一种基于衰减全内反射（ATR）的电光聚合物光调制器。该调制器由棱镜-金属-电光-聚合物-金属多层结构组成。在EO聚合物层上施加的电场以固定角度将入射光的能量耦合效率电调制为导波共振。与传统的基于表面等离子体共振的ATR调制器相比，该调制器的驱动电压由于新的工作内角的选择而大大降低。它还提供了在插入损耗和孔径尺寸方面优于用于准直光束的振幅调制的其他技术的优点。
An improved electro-optic (EO) polymer light modulator based on attenuated-total-internal-reflection (ATR) is demonstrated. The modulator consists of a prism–metal–EO-polymer–metal multilayer structure. An applied electric field across the EO polymer layer electrically modulates the energy coupling efficiency of incoming light into guided wave resonance at fixed angles. Compared with conventional ATR modulators based on surface plasmon resonance, the driving voltage for this modulator has been greatly reduced because of the newly chosen working interior angle. It also offers advantages in terms of insertion loss and aperture size over other techniques for the amplitude modulation of a collimated light beam.
