Abstract
A photon source comprising a photon source body, said photon source body comprising at least one quantum dot; carrier injection means for injecting carriers into said at least one quantum dot and change of state means for changing the state of the carriers within the quantum dot after a predetermined time duration, the carrier injection means injecting carriers which are configured to allow emission of radiation by radiative recombination

A photon source comprising
- a photon source body, said photon source body comprising at least one quantum dot;
- carrier injection means for injecting carriers into said at least one quantum dot and change of state means for changing the state of the carriers within the quantum dot after a predetermined time duration, the carrier injection means injecting carriers which are configured to allow emission of radiation by radiative recombination.
A method of operating a photon source, the photon source comprising at least one quantum dot, the method comprising applying an electrical bias across said source to inject carriers into the at least one quantum dot to allow electrically activated emission from said at least one dot;
- and changing the state of carriers within the quantum dot after a predetermined time duration.
A method of operating a photon source, the photon source comprising at least one quantum dot, the method comprising applying an electrical bias across said source, optically exciting the source such that carriers are injected into the at least one quantum dot and changing the state of carriers within the quantum dot after a predetermined time duration.
