This thesis breaks new ground in the physics of photonic circuits
for quantum optical applications. The photonic circuits are based
either on ridge waveguides or photonic crystals, with embedded
quantum dots providing the single qubit, quantum optical emitters.
The highlight of the thesis is the first demonstration of a
spin-photon interface using an all-waveguide geometry, a vital
component of a quantum optical circuit, based on deterministic
single photon emission from a single quantum dot. The work makes a
further important contribution to the field by demonstrating the
effects and limitations that inevitable disorder places on photon
propagation in photonic crystal waveguides, a further key component
of quantum optical circuits. Overall the thesis offers a number of
highly novel contributions to the field; those on chip circuits may
prove to be the only means of scaling up the highly promising
quantum-dot-based quantum information technology.
