Linear and nonlinear characteristics of devices using millimeter-scale spools of highly nonlinear fiber are experimentally investigated within 2000-2400nm spectral range. Coils with radius larger than 3.5 mm indicate that macro-bending induced radiation loss is negligible up to 2400nm. Devices with smaller diameter coiling resulted in macro-bending losses that dominate over micro-bending losses beyond 2200nm. A tunable short-wave infrared source was constructed using a coin-sized fiber module to demonstrate an efficient nonlinear conversion from 1.26 to 2.2 microm.
在2000-2400nm光谱范围内，对使用毫米级高度非线性光纤线轴的器件的线性和非线性特性进行了实验研究。半径大于3.5mm的线圈表明，在2400nm以下，宏观弯曲引起的辐射损耗可忽略不计。直径较小的线圈制成的器件在2200nm以上会导致宏观弯曲损耗超过微观弯曲损耗。使用硬币大小的光纤模块构建了一个可调谐短波红外源，以演示从1.26到2.2微米的高效非线性转换。
