Silicon optical fibers are a promising platform for supercontinuum (SC) generation in the near-to-mid infrared (1.3 - 4.5nanoseconds) to be used for sensing and spectroscopy. This project aims to develop an accurate numerical model that takes into account the wavelength dependence of the key parameters, including multi-photon absorption and free-carrier absorption, in order to better understand the dynamics of the continuum generation. This will then be used for the optimisation of these fibers, including the design of tapered profiles (which have a variation of diameter along the length) that can produce a wider SC than previously achieved, and at the lowest possible powers.

硅光纤是一个很有前途的平台，用于产生近中红外（1.3 - 4.5纳秒）的超连续谱（SC），用于传感和光谱学。该项目旨在开发一个精确的数值模型，该模型考虑到关键参数的波长依赖性，包括多光子吸收和自由载流子吸收，以便更好地理解连续谱产生的动力学。这将用于优化这些纤维，包括锥形轮廓的设计（其直径沿长度沿着变化），其可以产生比以前实现的更宽的SC，并且功率尽可能低。
