摘要
利用非线性偏振旋转锁模掺铒光纤激光器和1100m长的掺锗硅基高非线性光纤制作了超连续光源,获得了从1150~1750nm的超宽带输出光谱,其中1150~1350nm波段光谱起伏小于3dB,1600~1700nm波段平坦度优于1dB,并有很好的向长波延展空间。光谱展宽的机理为孤子分裂与受激拉曼散射,而四波混频使光谱进一步展宽。
Abstract
A supercontinuum generation in 1100 m germano-silicate high nonlinear fiber is demonstrated. An ultra-broadband supercontinuum of 1150~1750 nm is achieved. The ripple between 1150 nm and 1350 nm is less than 3 dB, and the ripple between 1600 nm and 1700 nm is less than 1 dB. The supercontinuum is expected to extend broadly in wavelength over 1750 nm. A nonlinear Schr?dinger equation model is adopted to indicate the spectral broadening mechanism is soliton fission and stimulated Raman scattering in soliton, and four wave mixing also plays an important role.
