A novel electro-optic multiplier is proposed, which can perform voltage multiplication operation by use of the Kerr medium exhibiting dual transverse electro-optic Kerr effect. In this kind of Kerr medium, electro-optic phase retardation is proportional to the square of its applied electric field, and orientations of the field-induced birefringent axes are only related to the direction of the field. Based on this effect, we can design an electro-optic multiplier by selecting the crystals of 6/mmm, 432, and m3m classes and isotropic Kerr media such as glass. Simple calculation demonstrates that a kind of glass-ceramic material with a large Kerr constant can be used for the design of the proposed electro-optic multiplier.
提出了一种新型电光倍增器，它可以利用呈现双横向电光克尔效应的克尔介质来执行电压倍增操作。在这种克尔介质中，电光相位延迟与其施加电场的平方成正比，并且场致双折射轴的方向仅与电场方向有关。基于这种效应，我们可以通过选择6/mmm、432和m3m晶类的晶体以及诸如玻璃等各向同性克尔介质来设计电光倍增器。简单计算表明，一种具有大克尔常数的微晶玻璃材料可用于所提出的电光倍增器的设计。
