Abstract

We show that four-wave mixing in semiconductor optical amplifiers with the use of two orthogonally polarized pumps offers the possibility of frequency conversion with constant efficiency over several terahertz. The same two-pump configuration permits one to convert the signal to lower or higher frequencies with the same efficiency.
