Abstract

We demonstrate efficient Bragg-scattering four-wave mixing frequency conversion in a few-mode fiber with two pumps spectrally separated from the signal and idler by 600 nm. The wideband frequency conversion is made possible by propagating the frequency components in two different spatial modes, the pumps are excited in the LP11 mode, while the signal is excited in the LP01 mode, and the Bragg scattering (BS) idler is generated in the LP01 mode. For these processes, we experimentally characterize their conversion efficiency and bandwidth. The dependency of conversion efficiency on peak pump power and the separation between BS components are measured, demonstrating a peak conversion efficiency of up to 79%.
