Tuneable frequency up-conversion based on biased asymmetric coupled quantum well structure
The behaviours of the optical nonlinear susceptibility X(3) responsible for the phaseconjugate beam of frequency conversion in nondegenerate four-wave mixing (NDFWM) are studied for a biased asymmetric coupled quantum well (ACQW) structure. It is shown that the frequency upconversion peak position determined by X(3) is very sensitive to the external inverse electric field strength applied among the grown direction of quantum well but its value is insensitive to that. In other words, the frequency up-conversion peak has a large shift but its value maintains a constant when the electric field strength increases in a small bias range. The characteristics of the tuneable-frequency and the power balance of the ACQW structure may provide the high-efficient wavelength conversion in the optical communication system.
