Recent Research projects


I have established and currently leading a biosensing project in collaboration with the university of Cambridge to investigate the detection of biomolecules with photonic devices. This involves simulating, designing and fabricating nanophotonics devices, the use of inkjet printing [1] and the preparation of solutions containing biomolecules such as DNA or proteins. The project could lead to earlier detection of cancerous cells and a better understanding of cell-cell communication.


Past Research projects


All-optical spatial registration of optically active QDs with nanometre accuracy [2-3]. Integration of an array of micropillars for "plug and play" single photon source [4]. Light guiding in a nanobelt [5] and tapered nanowire [6]. Strongly coupled single quantum dot in a cavity embedded in a photonic crystal waveguide [7]. Novel all optical QD registration technique for cavity quantum electrodynamics with photonic crystals [8]. Investigation of photonic molecule design for light-matter interaction and optical switching [9].
