Simulation of Emission Wavelength of Quantum Dot Based Single Photon Sources
Advances in quantum information processing and the requirements of quantum key distribution schemes have made high quality single photon sources, extremely essential. Here generation of a single photon from a semiconductor quantum dot using a semi-classical approach is investigated. Finite Element Method is used for the Eigen mode analysis of a typical pyramidal semiconductor quantum dot [3]. A design methodology is also proposed for obtaining the required emission wavelengths. Additionally, effects of wetting layer, height to base ratio and strain due to lattice mismatch are investigated. An Empirical relationship is obtained between pyramid geometry and emission wavelength. The simulation results were verified against the experimental works including [7] in ${1.2} \mu m$ to ${1.3} \mu m$ emission regime, and good match was observed.
