Abstract
A detection device can include a cavity structure forming a Fabry-Perot optical microcavity, an electrostatic trap, and a Brownian motor. The Fabry-Perot optical microcavity has two mirrors extending on each side of a reference plane in a spacer region between the two mirrors. The mirrors are configured to vertically confine radiation in the spacer region, e.g., with respect to a first direction perpendicular to the reference plane. The electrostatic trap is arranged in the spacer region. The trap includes a pit and the cavity structure is generally configured to confine radiation in the pit, laterally (e.g., with respect to a second direction parallel to the reference plane). The Brownian motor structure extends in the spacer region along said reference plane. This structure is adapted to laterally load particles in the pit of the electrostatic trap by moving such particles along the structure, in operation.
