Targeted pulse-energy routing in fibers play a key role in driving nonsupercontinuum applications. The key strategy to promote supercontinuum generation is to match the zero-dispersion wavelength (ZDW) of the fiber with the laser wavelength so that the input pulse sustains a high peak intensity over a long fiber length to enhance all the nonlinear optical processes. Targeted routing of femtosecond pulse energy (TRFPE) can be achieved by detuning the ZDW of the fiber far away from the laser wavelength. The latest developments have helped in realizing robust TRFPE under short nonlinear-interaction conditions through intermodal four-wave mixing (FWM) and soliton mediated Chrenkov radiation. It is observed that more than 7% conversion efficiency is obtained from the pump input to the yellow 586 nm signal under short-interaction conditions. This results in the generation of a multimilliwatt-level signal without being contaminated by supercontinuum generation.
