Improved flatness of a supercontinuum at 1.55 microns in tapered microstructured optical fibres

Description/Abstract

Supercontinuum (SC) generation occurs when high-power ultrashort optical pulses propagate through a nonlinear optical medium and it has been investigated since 1970s [1]. Microstructured optical fibres (MOFs) have enabled major advances in obtaining SC spectral broadening over the past decade, leading to the development of new inexpensive and efficient sources. Low cost SC will find new applications in diverse areas such as telecommunications, optical frequency metrology, spectroscopy etc. [1]
