Abstract

A record 730 nm parametric conversion in silica fiber from the near-infrared to the short-wave infrared band is reported and analyzed. A parametric gain in excess of 30 dB was measured for a signal at 1300 nm (with corresponding idler at 2030 nm). This conversion was performed in a travelling single-pass one-pump parametric architecture and high efficiency is achieved by a combination of high peak power and a nonlinear fiber with a reduced fourth-order dispersion coefficient.

摘要

报道并分析了在石英光纤中从近红外波段到短波红外波段创纪录的730纳米参量转换。对于1300纳米处的信号（相应的闲频光在2030纳米处），测得的参量增益超过30分贝。这种转换是在单通道单泵浦参量结构中进行的，通过高峰值功率和具有降低的四阶色散系数的非线性光纤相结合实现了高效率。
