Introduction of CPDS

Centre for Photonic Devices and Sensors (CPDS) is in the Photonics area of the Electrical Engineering Division, with a research focus embracing photonic and sensing devices, functional materials and their integration at system level.

We aim to address future societal needs with new system functionalities through invention of novel device architectures based on in-depth understanding of basic material properties.

There is a wide range of activities within the group, including phase-only holography and its applications, high brightness multi-stable colour reflective displays, tunable dielectric materials and devices for radio frequencies, liquid crystal on silicon (LCOS) device development, and novel sensors.

As well as conducting highly focused studies, we also specialise in the development of demonstrators for business exploitation and commercialisation. This is facilitated by multi-disciplinary expertise within the group and by our highly experienced team approach. Some of the outcomes from the group have been successfully transferred to our industrial collaborators for production.
