Spatio-spectral analysis of supercontinuum generation in higher order electromagnetic modes of photonic crystal fiber.


The far-field spatial distributions of higher order electro-magnetic mode supercontinua were resolved spectrally and recorded. The supercontinua were created by precise control and direction of input pump energy offset axially from the photonic crystal fiber core. By processing the measured spectra, the spatial mode shape at each wavelength was determined… (More)
