Abstract

一种偏振模式转换器，包括矩形波导(101)、第一渐变波导(102)和第二渐变波导(l03)。矩形波导(101)的高度为第一高度H1。第一渐变波导(102)的一边和矩形波导(101)相连。第一渐变波导(l02)的宽度逐渐变化。第一渐变波导(102)的高度为第二高度H2，第二高度H2小于第一高度H1。第二渐变波导(103)和矩形波导(101)不相连，第二渐变波导(103)和第一渐变波导(102)不相连。第二渐变波导(103)的宽度逐渐变化。第二渐变波导(103)的高度为第一高度H1。第二渐变波导(103)的第一端和矩形波导(101)之间的距离为第一距离，第二渐变波导(103)的第二端和矩形波导(101)之间的距离为第二距离，第二距离大于第一距离。第一渐变波导(102)位于矩形波导(101)和第二渐变波导(103)之间。
