Abstract

A broad and flat spectrum is preferable in many applications of supercontinuum sources. However, supercontinuum generation based on modulational instability often exhibits a prominent narrow blue peak followed by a significant dip in the neighboring longer-wavelength region. In this numerical study, we present a mitigation strategy based on modulating the pump power. Using as little as three pulses in the modulation scheme, we demonstrate the ability to improve the flatness by a factor of three, while simultaneously lowering the peak power of each pulse, which is desirable from the perspective of fiber degradation.
