我们报告了使用倒肋设计在聚二乙炔的自旋膜中制造单模通道波导。这些坚固的导向器由旋涂在玻璃基板上的聚二乙炔平面层组成，其中高折射率通道已通过离子交换定义。这种波导的模型表明，导波的大部分光场被限制在聚合物层中，高折射率玻璃通道提供横向限制。将1.06、1.15、1.32和1.55 μm的光端射耦合到复合波导中，导致光被限制在聚合物层中的单模波导。这种形成波导的方法应该适用于广泛的聚合物材料。
We report the fabrication of single‐mode channel waveguides in spun films of polydiacetylenes using an inverted rib design. These robust guides consist of a planar layer of the polydiacetylene spun on a glass substrate in which high‐index channels have been defined by ion exchange. Models of such guides show that most of the optical field of the guided wave is confined to the polymer layer, with the high‐index glass channels providing lateral confinement. End‐fire coupling of 1.06, 1.15, 1.32, and 1.55 μm light into the composite guides resulted in single‐mode guiding with the light confined to the polymer layer. This approach to waveguide formation should be applicable to a wide range of polymeric materials.
