Polarisation-selective reconfigurability in hybridised-active-dielectric nanowires

A representation of polarised photons being absorbed into functional nanowires

June Sang (Jason) Lee is the lead author of a new paper in Sciences Advances*, which explains how multiple polarisation channels were used to carry out parallel processing, which enhanced computing density by several orders over conventional electronic chips.


Jason and his colleagues in the Bhaskaran Lab and in Exeter developed a hybridised-active-dielectric nanowire, and captured different polarisations of light, which do not interact with each other.  Each polarisation can therefore be used as an independent information channel, which enables more information to be stored in multiple channels.

'We all know that the advantage of photonics over electronics is that light is faster and more functional over large bandwidths.  So, our aim was to fully harness such advantages of photonics combining with tunable materials to realise faster and denser information processing".
