| 摘 要： | 以亚毫米尺度的铌镁酸铅-钛酸铅(PMN-PT)透明陶瓷片为导波层制备了对称金属包覆波导,并利用自由空间耦合技术激发了波导中的超高阶导模.根据衰减全反射(ATR)峰的移动,得到了在波导两侧所施加电压与光强反射率的关系,从而计算了PMN-PT透明陶瓷片的二次电光系数.

| Abstract: | Ultrahigh-order guide modes are excited by employing the free-space coupling technique in a symmetrical metal-cladding optical waveguide fabricated with a submillimeter-scale transparent PMN-PT ceramics.The voltage-dependent variation of the reflectivity of the light intensity is obtained according to the shift of the attenuated total reflection(ATR) resonance dip and the quadratic electro-optic coefficient of the transparent PMN-PT ceramics is then calculated. |
