NON-RECIPROCAL OPTICAL TRANSMISSION DEVICE AND OPTICAL APPARATUS INCLUDING SAME

Nonreciprocal optical transmission devices and optical apparatuses including the nonreciprocal optical transmission devices are provided. A nonreciprocal optical transmission device includes an optical input portion, an optical output portion, and an intermediate connecting portion interposed between the optical input portion and the optical output portion, and comprising optical waveguides. A complex refractive index of any one or any combination of the optical waveguides changes between the optical input portion and the optical output portion, and a transmission direction of light through the nonreciprocal optical transmission device is controlled by a change in the complex refractive index. 提供了非互易光传输器件及包括该非互易光传输器件的光学装置。种非互易光传输器件包括光输入部分、光输出部分、以及插置在光输入部分与光输出部分之间并包括光波导的中间连接部分。光波导中的任何个或任何组合的复折射率在光输入部分与光输出部分之间变化，并且经过非互易光传输器件的光的传输方向由复折射率的变化控制。
