Broadband Supercontinuum Generation by Bridging Two Separate Supercontinua Pumped at Two Different IR Wavelengths

摘要

We demonstrate a broad supercontinuum source by bridging two separate supercontinua that are pumped at two different IR wavelengths. Two separate supercontinua are overlapped to form a broadband supercontinuum source without spectrum discontinuity between two different pumping sources. The bridging effect of two separate supercontinua is successfully demonstrated by applying two pumping sources at 1460 nm and 1769 nm into a regular single mode fiber. Also, more than 1000 nm expansion possibility due to the bridging effect can be achieved by pumping at 1350 nm and 1963 nm.
