Abstract

The generation of an octave spanning supercontinuum covering 488-978 nm (at -30 dB) is demonstrated for the first time on-chip. This result is achieved by dispersion engineering a 1-cm-long Si3N4 waveguide and pumping it with an 100-fs Ti:Sapphire laser emitting at 795 nm. This work offers a bright broadband source for biophotonic applications and frequency metrology.

摘要

首次在芯片上实现了覆盖488 - 978 nm（-30 dB）的倍频程超连续谱的产生。该结果是通过对一条1厘米长的Si3N4波导进行色散工程设计，并使用波长为795 nm的100飞秒钛宝石激光器泵浦实现的。这项工作为生物光子学应用和频率计量提供了一个明亮的宽带光源。
