Active Multiplexing of Spectrally Engineered Heralded Single Photons in an Integrated Fibre Architecture (Springer Theses) - Softcover

Über die Autorin bzw. den Autor

Dr Robert Francis-Jones received his PhD from the University of Bath in 2016 for his work on multiplexing high-purity heralded single photon sources under the supervision of Dr Peter Mosley, for which he received the Institute of Physics Quantum Electronics and Photonics Doctoral Thesis Prize 2017.

His main research areas include the design and fabrication of photonic crystal fibres (PCF) for photon pair generation in PCF for use in heralded single photon sources, and quantum frequency translation of single photons from the visible to the infrared.  His other research interests include, numerical modelling of nonlinear optical processes such as four-wave mixing,  the development of field programmable gate array designs for photon counting and fast feed forward optical switching schemes and the development of antiresonant hollowcore optical fibres for quantum optics applications.

Von der hinteren Coverseite

This clearly written thesis discusses the development of a highly innovative single-photon source that uses active optical switching, known as multiplexing, to increase the probability of delivering photons into a single mode. Improving single-photon sources is critical in advancing the state of the art in photonic quantum technologies for information processing and communications.
