Engineering the Collapse of Lifetime Distribution of Nitrogen-Vacancy Centers in Nanodiamonds
Hao Li, Jun-Yu Ou, Behrad Gholipour +4
We demonstrate experimentally that the distribution of the decay rates of nitrogen-vacancy centers in diamond becomes narrower by over five times for nanodiamonds embedded in thin…
All-dielectric free-electron-driven holographic light sources
Brendan P. Clarke, Behrad Gholipour, Kevin F. MacDonald +1
It has recently been shown that holographically nanostructured surfaces can be employed to control the wavefront of (predominantly plasmonic) optical-frequency light emission gener…
Femtosecond laser inscription of nonlinear photonic circuits in Gallium Lanthanum Sulphide glass
María Ramos Vázquez, Belén Sotillo, Stefano Rampini +6
We report on femtosecond laser writing of single mode optical waveguides in chalcogenide Gallium Lanthanum Sulphide (GLS) glass. A multiscan fabrication process was employed to cre…
Chalcogenide hyperbolic metamaterial with switchable negative refraction
Harish N. S. Krishnamoorthy, Behrad Gholipour, Nikolay I. Zheludev +1
Chalcogenide glasses are exceptional materials that show a wide contrast in optical properties upon phase change and are highly researched for reconfigurable electronic and nanopho…
All-dielectric phase-change reconfigurable metasurface
Artemios Karvounis, Behrad Gholipour, Kevin F. MacDonald +1
We harness non-volatile, amorphous-crystalline transitions in the chalcogenide phase-change medium germanium antimony telluride (GST) to realize optically-switchable, all-dielectri…
Optically Reconfigurable Photonic Devices
Qian Wang, Edward T. F. Rogers, Behrad Gholipour +4
Optoelectronic components with adjustable parameters, from variable-focal-length lenses to spectral filters that can change functionality upon stimulation, have enormous technologi…
n-Type Chalcogenides by Ion Implantation
Mark A. Hughes, Yanina Fedorenko, Behrad Gholipour +8
Carrier-type reversal to enable the formation of semiconductor p-n junctions is a prerequisite for many electronic applications. Chalcogenide glasses are p-type semiconductors and…
