Abstract
We theoretically demonstrate optical pulsation based on optical near-field interactions between quantum nanostructures. It is composed of two quantum dot systems, each of which consists of a combination of smaller and larger quantum dots, so that optical excitation transfer occurs. With an architecture in which the two systems take the role of a timing delay and frequency up-conversion, we observe pulsation in populations pumped by continuous-wave light irradiation. The pulsation is induced with suitable setting of parameters associated with the optical near-field interactions. This will provide critical insights toward the design and implementation of experimental nanophotonic pulse generating devices.
