N2 - Using femtosecond upconversion we investigate the time andwavelength structure of infrared supercontinuum generation. It is shownthat radiation is scattered into higher order spatial modes (HOMs) whengenerating a supercontinuum using fibers that are not single-moded, such asa step-index ZBLAN fiber. As a consequence of intermodal scattering andthe difference in group velocity for the modes, the supercontinuum splits upspatially and temporally. Experimental results indicate that a significant partof the radiation propagates in HOMs. Conventional simulations of supercontinuum generation do not include scattering into HOMs, and includingthis provides an extra degree of freedom for tailoring supercontinuumsources.
