Programmable photonic circuits that can implement linear transformation between any number of input and output optical channels are used both for quantum computation in quantum optics and for signal processing in telecommunications. These “universal multiport interferometers” can be built using meshes of reconfigurable beam splitters, for example on an integrated photonic platform.

Researchers at the University of Oxford have demonstrated, for the first time, how to use molecules to manipulate the surface of a ‘topological insulator’, an exotic material with unusual electronic properties. Understanding and manipulating these properties is a notable step towards the innovative information transfer and storage promised by ‘spintronics’.

Signal couplers allow signals from two transmission lines to be combined and/or split, and can be used in a variety of applications including power distribution networks, sensor arrays, and astronomical instrumentation. Conventional couplers have both transmission lines, which carry the signal, running in parallel to each other, which makes them unsuitable for circuits that require signal path crossing or bypassing, particularly in applications in a linear array. Traditionally this is overcome by using cross-guide coupler, additional cabling or series of optical free-space beam splitters.

Researchers from the University of Oxford have for the first time mapped the magnetic interactions of an artificial garnet known as YIG (yttrium iron garnet). This understanding could pave the way for the ‘magnonics’ revolution, which offers an entirely new way to transfer data.

The new edition of the Oxford Physics Newsletter showcases commercialisation of technology invented for fundamental particle physics experiments and is now being used in applications across the hi-tech manufacturing sector. The article describes how we collaborated with industry to bring this exciting precise measurement technology to market. We also recount the story of Oxford Physics’ first ever spin-out company, the now hugely successful Oxford Instruments plc.
