摘要

我们提出了几种方法来控制埋地通道波导的弯曲损耗。它们是基于在包层中引入稍微不同指数的附加层。在某些应用中，例如开关或传感，在“主动”状态下增加弯曲损耗而不增加“被动”状态下的弯曲损耗可能很重要。本文给出了一种基于弯曲通道波导的可变光衰减器的改进设计，作为应用该策略的一个例子。

Effect of added layers on bend loss in buried channel waveguides

We propose a number of ways to control bend loss in buried channel waveguides. They are based on the introduction of additional layers with slightly different indices in the cladding. In some applications, such as switching or sensing, it may be important to increase the bend loss in the 'active' regime without increasing it in the 'passive' regime. An improved design of a variable optical attenuator, based on a bent channel waveguide, is presented as an example of applying this strategy.
