A ultra broad tunable wavelength converter based on four wave mixing with two orthogonal pump in a semiconductor optical amplifier (SOA) fiber ring laser is demonstrated.This scheme has approximate flat conversion efficiency in a wavelength shift range of more than 50nm.Measured SOA gain and amplified spontaneous emission (ASE) noise show that conversion efficiency is proportional to the pump power under some limitation conditions.
