New approaches to optical systems open up solutions not previously available, particularly allowing low-cost high-performance functions.

3D-printed optical microscope
Using a low cost 3D printer and a Raspberry Pi $20 computer with a mobile phone camera module, we make research grade microscopes. Capable of micron resolution, and with sub-100nm control in x,y,z directions these are extremely useful for bio-applications. For instance, instead of building expensive life-support boxes in a research microscope to keep cells alive, our low-cost (<$100) disposable microscopes can operate inside standard incubator. Currently we are exploring the potential for such systems to check for bacterial contamination in water in Tanzania (Waterscope).

Dynamical optical circuits

Most information is sent as light through optical fibres, but processed and routed through electronic circuits.  This conversion costs power (~10% of the world’s electricity) and speed.  The internet is growing rapidly and shows no signs of slowing down. Our research aims to create faster, lower-power components that will route and process information directly as light, in optical circuits that can be rewritten as easily as changing the picture on a computer monitor.  One way this will improve capacity is by allowing MIMO, a technique currently used to speed up wireless networks, to be used in fibre optic cables to boost their bandwidth.

Using dynamic optical circuits, we can perform quantum optical experiments on light in many-dimensional quantum states. We aim to shape light through complex environments such as biological tissue andmicroscopic endoscopes, with applications in medicine and biology.

NanoPhotonics Christmas Party

16 December 2021

Many thanks to Chris and Jeremy for organising a very nice Christmas dinner at Jesus College. It was good to be able to see everyone again. Now we just need to figure out who gave which present to who :) Christmas_dinner_2021_2 Christmas_dinner_2021_3

Bowling November '21

29 November 2021

A nice evening out with the NanoPhotonics group. About 30 people from the NanoPhotoncis centre decided to go bowling together at the Leisure Centre. And ofcourse pub afterwards. Thanks to the organizers Sarah and Ishaan.
