Ultra wide band supercontinuum generation in air-silica holey fibers by SHG-induced modulation instabilities

Open Access Open Access

Abstract

Second harmonic generation in an air-silica microstructured optical fiber pumped by subnanosecond pulses is used in order to initiate modulation instability processes in normal and anomalous dispersion regimes. This allows us to generate an ultra wide and flat supercontinuum (350–1750 nm), covering the entire transparency window of silica and exhibiting a singlemode transverse profile in visible range.
