Spontaneous emission of light is essential to quantum optics in design and development of high efficiency optical devices which are useful in quantum optical telecommunication and to diverse applications such as Optical Time-Division-Multiplexing (OTDM), Wavelength-Division Multiplexing (WDM), Optical Switch, Super Lens, Laser, LED and Single Photon Source (SPS). The triangular lattice and square lattice have been proposed for security optical communication system. However, these simulations and experiments are faced many obstacles. Thus, we performed to develop an efficient single photon source by controlling spontaneous emission of the photon using two-dimensional silicon-based photonic crystal with honeycomb lattice. A quantum dot embedded in planar photonic crystal membrane waveguide is the light source. The honeycomb lattice of circular air hole on silicon plate is simulated to obtain completely large photonic band gaps. This significant property shows the potential applied with waveguide or cavity structures for controlling spontaneous emission between the quantum dots and the photonic crystal waveguide. Significantly, this work is oriented to produce the novel single photon sources which can emit one photon at a time for the quantum optical security network with single photon state. In addition to the honeycomb lattice can easily be made on a Si on insulator (SOI) wafer.
We apply a magnetic field to photonic crystal cavity devices with embedded Indium Arsenide (InAs) quantum dots (QDs), and demonstrate strong coupling between individual QD exciton spin states and a photonic crystal ca...
