Pockels effect principle
WebSCQDs, the origin of SHG and Pockels effects is not the lack of an inversion center; instead it is (1) the quantum-confinement effect, (2) surface effects, and (3) defect and trap states. As the sizes of SCQDs are small enough to be comparable with their exciton Bohr radii, quantum-confinement effects predomi-nate.6,7 WebThe Pockels effect is an extremely fast physical mechanism, hence in principle external modulation is capable of achieving extremely high speeds.
