ABSTRACT:
Optical signal frequency conversion and mixing is accomplished by an optical device comprised of a photodetector, a non-linear device, passive circuitry, and a multiple quantum well structure. The photodetector converts a light signal into an electrical signal. The non-linear devices create harmonics of the electrical signal of which the passive circuitry selects a desired frequency of the harmonics. This selected frequency in turn modulates the multiple quantum well structure. A power bias is applied to the multiple quantum well structure which is then modulated by it to produce a modulated output light beam modulated at the selected frequency.
