Abstract

We propose an erbium-doped fiber ring laser whose multi-wavelength oscillation is tunable and switchable by tuning fiber bragg gratings. By applying axial pressure on the fiber bragg grating, the wavelength spacing of the proposed laser can be tuned continuously. And by adjusting a polarization controller(PC), the proposed laser can be switched among dual-, triple- and four-wavelength lasing operations.

여러 개의 광섬유격자를 가변하여 파장변환과 스위칭이 가능한 다파장 EDF 링레이저를 제안하였다. 광섬유격자에 인가되는 압력을 변화시킴으로써 EDF 링레이저의 출력파장과 파장간격을 연속적으로 변환시킬 수 있었으며, 편광조절기를 조절하여 EDF 링레이저의 출력파장을 두 파장, 세 파장 또는 네 파장으로 스위칭 할 수 있었다.
