Fluorotellurite microstructured fibers (MFs) based on TeO2-BaF2-Y2O3 glasses are fabricated by using a rod-in-tube method. Tapered fluorotellurite MFs with varied transition region lengths are prepared by employing an elongation machine. By using a tapered fluorotellurite MF with a transition region length of ∼3.3 cm as the nonlinear medium and a 1560 nm femtosecond fiber laser as the pump source, broadband supercontinuum generation covering from 470 to 2770 nm is obtained. The effects of the transition region length of the tapered fluorotellurite MF on supercontinuum generation are also investigated. Our results show that tapered fluorotellurite MFs are promising nonlinear media for generating broadband supercontinuum light expanding from visible to mid-infrared spectral region.
基于TeO2-BaF2-Y2O3玻璃的氟碲酸盐微结构光纤（MFs）采用管中棒法制备。通过使用拉伸机制备了具有不同过渡区长度的锥形氟碲酸盐MFs。以过渡区长度约为3.3 cm的锥形氟碲酸盐MF为非线性介质，1560 nm飞秒光纤激光器为泵浦源，获得了覆盖470至2770 nm的宽带超连续谱。还研究了锥形氟碲酸盐MF的过渡区长度对超连续谱产生的影响。我们的结果表明，锥形氟碲酸盐MF是用于产生从可见光扩展到中红外光谱区域的宽带超连续光的有前途的非线性介质。
