Technological challenges involved with achieving a scalable quantum photonic circuit are addressed through the design, development and testing of controllable on-chip nano-photonic elements, such as nanobeam photonic crystal filters and electro-mechanical actuators. The research into both of these types of devices presented here represents the first work of this kind that has been carried out in the LDSD group at the University of Sheffield. The majority of the measurements that have been undertaken and which are presented here are of an optical spectroscopic nature. An on-chip optical filter based on a one-dimensional photonic crystal structure has been modelled and demonstrated exper...

Switching is achieved by electro-mechanical actuation of an integrated directional coupler.

Associated with this is the halt to the delivery of the practical experience required of engineering students. The Multidisciplinary Engineering Education (MEE) team at The University of Sheffield have responded to this problem in an efficient and effective way by recording laboratory experiences and putting videos, quizzes and data online for students to engage with. The focus of this work was on ensuring all Learning Outcomes (LOs) for modules and courses were preserved. Naturally, practical skills cannot be easily provided using this approach, but it is an effective way of getting students to interact with real data, uncertainty and equipment which they cannot access directly. A number of short case studies from across the range of engineering disciplines are provided to inspire and guide other educators in how they can move experiments on line in an efficient and effective manner.
