As one approach to address the problem, the feasibility of integrating reflective optics into ion trap to increase free-space photon interception is studied. The development and operation of two novel ion traps are demonstrated: one integrates a spherical mirror with a linear quadrapole trap, and the other combines the optical surface with the RF electrode. The possibility of using aspherical optics to improve ion images is studied and partially implemented. A continuously excited single photon source based on 138Ba+ ion is demonstrated and calibrated. Methods of scaling up current design are also discussed.Thesis
