Wide Bandgap Nanophotonics

Our lab is focused on nanoscale engineering and characterization of quantum entities to control and guide light at the nanoscale. We are exploring several research directions to understand light – matter interactions and to fabricate energy efficient devices.

Single Emitters in 3D mateirlas We are constantly looking for novel single photon emitters that exhibit narrow spectral width and short excited state lifetime. Point defects in wide bandgap materials (diamond, SiC) are the main players in the game, but other candidates are always welcome. These emitters are our potential quantum bits (quits)

Single Emitters in 2D mateirlas. We develop new strategies to engineer single emitters in 2D materials. so far our efforts were focused on 2D hBN, that host optically stable quantum emitters in room temperature. (see T. Tran et al., Nature Nanotechnology 11, 37 (2016)

Optical Cavities Optical cavities are important building block of any nanophotonics network. Fabrication of photonic crystal cavities and microdisk resonators is challenging. However, our lab will aim to produce the highest quality devices our of widebandgap semiconductors such as GaN, Diamond and SiC

Devices In the realm of the 21st century we always improve the performance of our devices. We require faster communications, powerful lasers and brighter light sources – all with reduced power consumption. Our lab is focused on engineering these new class of devices with enhanced functionalities such as low threshold lasers and ultra bright LEDs

Investigation of Light Matter Interaction Integrating single photon emitters with optical cavities provides an interesting platform for light-matter interaction and lies in the heart of quantum information processing. Our lab is focused on exploring this fascinating physics to demonstrate coupling of single emitters to optical cavities and understand the peculiar behavior of coupled photons.
