The active microcavity is adopted as an efficient source of nonclassical light. Using this device, excited with a mode-locked laser at a rate of 100 MHz, single photons are generated over a single field mode with a nonclassical sub-Poissonian distribution. Adiabatic recycling within a multistep Franck-Condon molecular optical-pumping mechanism, characterized by quantum efficiency close to 1, implies a pump self-regularization process leading to a striking
n-squeezing effect. Replicating the basic single-atom excitation process a beam of quantum photon
∣n〉 states (Fock states) can be created. This represents a significant advance in the fields of basic quantum-mechanical investigation, quantum communication, and quantum cryptography.

The process of adiabatic recycling within a multi-step Franck-Condon molecular optical-pumping mechanism, characterized in our case by a quantum efficiency very close to one, implies a pump self-regularization process leading to a striking n-squeezing effect. By a replication of the basic single-atom excitation process a beam of quantum photon (Fock states) can be created. The new process represents a significant advance in the modern fields of basic quantum-mechanical investigation, quantum communication and quantum cryptography.

Moreover, the microactivity has been adopted as active beam splitter in a novel Hanbury-Brown–Twiss configuration for the radiation taking place over the two output mirrors.
