Abstract

EDF를 증폭매체로 하는 광 증폭기에 관하여 기재되어 있다. 이는 에르븀이 도우프 된 증폭매체로서의 제1광섬유와 이 제1광섬유 사이에 접속되어 있는 사마륨의 도우프 된 제2광섬유를 포함하는 것을 특징으로 한다. 따라서, 광섬유만을 이용하여 증폭매체를 구성함으로써 광 증폭기의 구조를 더욱 간단하게 하였다.An optical amplifier using EDF as an amplifying medium is described. It is characterized in that it comprises a first optical fiber as an erbium doped amplification medium and a samarium doped second optical fiber connected between the first optical fiber. Therefore, the structure of the optical amplifier is further simplified by configuring the amplifying medium using only the optical fiber.
