New book published

‘Nano-photonics in III-V Semiconductors for Integrated Quantum Optical Circuits was recently published by Springer based on PhD Thesis of Nick Wasley.


  • Nominated as an outstanding Ph.D. thesis by the University of Sheffield, UK
  • Details current research at the forefront of experimental semiconductor physics, with applications in photonics and quantum information processing
  • Includes an insightful introduction to this experimental field written by a post-graduate researcher, for post-graduate researchers
  • Presents detailed descriptions of the micro-photoluminescence set-ups and optical spectroscopy experiments used to obtain the results discussed
  • 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.
