ABSTRACT:
In one aspect, the invention provides a defect multiple-quantum-well structure for manipulation of reflection and transmission of light by way of optical control of spatial distribution of electric field across the defect multiple-quantum-well structure. The defect multiple-quantum-well structure includes a pair of terminal multiple-quantum-well structures and a central multiple-quantum-well structure. The central multiple-quantum-well structure is sandwiched between the pair of terminal multiple-quantum-well structures. Each of the pair of terminal multiple-quantum-well structures has a band gap profile, and the central multiple-quantum-well structure has a band gap profile. The band gap profile of the central multiple-quantum-well structure is greater than the band gap profile of each of the pair of terminal multiple-quantum-well structures.
