Enhanced supercontinuum generation in highly nonlinear fibre by selected feedback seeding

Abstract

Abstract-. We propose a simple approach to control the supercontinuum generation, where a minute fraction of the output at specific positions was selected using a narrowband filter and then fed into a highly nonlinear fibre as the seeding light. We numerically investigated the influence of the feedback component on the supercontinuum generation. The results show the supercontinuum can be significantly enhanced with proper selected back seeding.
