Abstract

In this paper, we provide a theoretical prediction about the likelihood of producing high-order modes using, as far as we know, the simplest mode converter. The mode converter is a simple discontinuous waveguide for which reflection and transmission have recently been reported. As a result of the scattering of the fundamental guided mode (TE0), we have found that the high-order mode excitation is highly dependent on the position of the discontinuity. On the one hand, we discovered that in the presence of a discontinuity in the propagation direction, only even modes (TE0 and TE2) are excited, skipping the odd mode (TE1). When a lateral shift is considered, however, both even and odd higher-order modes (TE1 and TE2) are generated. Furthermore, after some lateral shifting, we found that only the pure TE2 mode is propagated.
波导不连续引起的高阶模式转换
在本文中,我们提供了一个关于使用最简单的模式转换器产生高阶模式的可能性的理论预测。模式转换器是一种简单的不连续波导,其反射和传输最近已被报道。由于基本导模(TE0)的散射,我们发现高阶模激发高度依赖于不连续的位置。一方面,我们发现,在传播方向上存在不连续性的情况下,只有偶模(TE0和TE2)被激发,跳过了奇模(TE1)。然而,当考虑横向偏移时,生成偶数和奇数高阶模式(TE1和TE2)。此外,在一些横向偏移之后,我们发现只有纯TE2模式被传播。
