我们提出并演示了一种全光纤宽带可调谐滤波器,利用谐振耦合光纤的弯曲具有“带阻”特性。与传统的阶跃折射率光纤弯曲诱导的“低通”滤波不同,采用这种新方法,我们能够保留“带阻”滤波特性,并在光纤设计固定短波长边缘的同时,调整被拒绝光谱带的长波长边缘。光纤滤波器可以很容易地与高功率单模输出掺镱或掺铥光纤激光器拼接和集成,以提供四波混频和/或受激拉曼散射的有效滤波,以及铒/镱共掺激光器中的寄生1um激光。
We proposed and demonstrated an all-fiber broadband tunable filter, with “band-stop” characteristics using bending of a resonant coupling fiber. Unlike conventional step-index fiber bend-induced “low-pass” filtering, with this novel approach we are able to retain the “band-stop” filter characteristics and tune the long wavelength edge of the rejected spectral band whilst the short wavelength edge is fixed by fiber design. The fiber filter can be readily spliced to and integrated with high-power single mode output ytterbium- or thulium-doped fiber lasers to provide efficient filtering of four-wave-mixing and/or stimulated Raman scattering, as well as parasitic 1um lasing in erbium/ytterbium co-doped lasers.
