摘要： A three-dimensional electro-optic waveguide is formed as a channel in a structure made of an organic non-linear optical polymer. A poling electric field is maintained in a portion of the polymer structure defining the channel, and the polymer structure is heated above the glass-transition temperature to enable dipolar moieties of the polymer to become aligned by the poling field. Heating continues until the dipolar moieties are sufficiently aligned to produce a higher index of refraction in the channel portion than in adjacent cladding portions of the polymer structure for at least one polarization of optical radiation propagating through the channel. The poling field is maintained as the polymer structure is then cooled below glass-transition temperature, thereby preserving alignment of the dipolar moieties (and hence preserving the differential index of refraction) in the channel portion of the polymer structure. Guided modes of optical radiation of at least one polarization can be supported in the channel.

摘要翻译： 在由有机非线性光学聚合物制成的结构中形成三维电光波导作为通道。 在限定通道的聚合物结构的一部分中保持极化电场，并且将聚合物结构加热到高于玻璃化转变温度以使聚合物的偶极部分通过极化场成对准。 继续加热，直到双极部分被充分对准，以在通道部分中产生比在聚合物结构的相邻包层部分更高的折射率，用于通过通道传播的光辐射的至少一个极化。 当聚合物结构然后冷却到低于玻璃化转变温度时，维持极化场，从而保持聚合物结构的通道部分中偶极部分的对准（并因此保持差示折射率）。 可以在通道中支持至少一个极化的光辐射的引导模式。
