This thesis details two types of deterministic solid-state quantum emitters, an optically-driven quantum dot source in a tapered nanowire waveguide, and an electrically-driven source implemented by integrating a single-electron pump into a two-dimensional p-n junction.
A finite-difference time-domain model of the optically-driven nanowire quantum dot source yielded optimized architectural parameters required to obtain a high transmission efficiency and a Gaussian far-field emission profile. An additional model of an electrically-gated nanowire source examined the effect of the surrounding structures on the emission properties of the source.
A successfully working prototype p-n junction device as a precursor to the electrically-driven quantum emitter was implemented by simultaneously inducing positive and negative two-dimensional carrier gases in an undoped semiconductor heterostructure. This device, fabricated in-house, offers a path forward in the development of a new class of bright, deterministic sources of single- and entangled-photons
