초록

광섬유 Bragg 격자의 외부에 주기적인 압력을 인가하여 여러 개의 파장을 반사시키는 샘플격자를 파장선택 소자로 이용하여 다파장 어븀 첨가 광섬유(Erbium-doped fiber, EDF) 링 레이저를 구현하였으며 압력의 주기를 변화시켜 발진파장간격을 가변하였다. 광섬유 Bragg 격자에 인가된 압력의 주기는 $200{\mu}m$, $580{\mu}m$, $1000{\mu}m$로 변화시켰으며, 이때 발진파장간격은 각각 4.1nm, 1.41nm, 0.82nm이었다.

Multi-wavelength Erbium-doped fiber(EDF) ring laser was developed by using a sampled fiber Bragg grating reflecting multiple wavelengths, which was formed by impressing periodical pressure on the outside of a fiber Bragg grating. The wavelength spacing was varied to 4.1nm, 1.41nm and 0.82nm, by pressing the grating with the pressure period $200{\mu}m$, $580{\mu}m$ and $1000{\mu}m$, respectively.
