Abstract
A device for generating photons includes a quantum box inserted into an optical cavity of micro-pillar type having at least one optical mode, the quantum box having at least one fundamental state and two states with one elementary excitation, the optical cavity having a bottom face and a top face, the bottom face bearing an electrical contact, the photon generation device advantageously comprises at least three electrical bonding pads electrically insulated from one another, arranged around the top face of the cavity.
Claims13
A device for generating photons comprising:
- a quantum box inserted into a first optical cavity having at least one optical mode and forming a diode, the quantum box having a fundamental state, two states with one elementary excitation, and a state with two elementary excitations, the quantum box being situated in an intrinsic region of the diode, the first optical cavity having a bottom face and a top face, the bottom face bearing an electrical contact;
- at least three electrical bonding pads that are electrically insulated from one another, arranged around the top face of the first optical cavity;
- and
- at least three adjustable voltage sources for applying respective and variable potential differences between each of said electrical bonding pads and the electrical contact borne by the bottom face of the first optical cavity.
