| Abstract | Abstract: Methods to improve single photon generation via photon-blockade in a photonic-crystal cavity with a strongly coupled quantum-dot are presented. With realistic system parameters, significant improvement in second-order-auto-correlation g2 (0) (from 0.93 to 0.79) is achieved. ©2009 Optical Society of America OCIS codes: (050.5298) Photonic crystals; (270.5585) Quantum information and processing Growing interest in making scalable Quantum Information Processors (QIP) combined with modern semiconductor fabrication technology resulted in numerous proposals for making cavity QED system in semiconductors. One of the major requirements of QIP is a non-classical light-source. We have previously demonstrated photon blockade in a photonic crystal – quantum dot (PhC-QD) system [1]; such an effect could be employed to make non-classical light sources on chip, but due to sub-optimal system parameters, only a limited blockade effect was achieved. Here we analyze a possibility of achieving a stronger photon blockade, and thus of achieving a stronger antibunching upon transmitting a coherent light beam tuned to the first order dressed states through such a system, within the constraints of the state of the art technology. If a QD is placed inside a cavity with two degenerate and orthogonal modes (which can be theoretically obtained in a cavity with C6 symmetry) and one of the modes is coherently driven by a laser, then the corresponding |
