Compressive optical imaging with a photonic lantern
Debaditya Choudhury, Duncan K. McNicholl, Audrey RepettI +4
The thin and flexible nature of optical fibres often makes them the ideal technology to view biological processes in-vivo, but current microendoscopic approaches are limited in spa…

High fidelity fibre-based physiological sensing deep in tissue
Tushar R. Choudhary, Michael G. Tanner, Alicia Megia-Fernandez +13
Physiological sensing deep in tissue, remains a clinical challenge. Here a flexible miniaturised sensing optrode providing a platform to perform minimally invasive in vivo in situ…

Modulation-assisted tunneling in laser-fabricated photonic Wannier-Stark ladders
Sebabrata Mukherjee, Alexander Spracklen, Debaditya Choudhury +4
We observe Wannier-Stark localization in curved photonic lattices, realized using arrays of evanescently coupled optical waveguides. By correctly tuning the strength of inter-site…
