An effective solid state photoluminescence by frequency constraint of cluster calculation
Akib Karim, Igor Lyskov, Salvy P. Russo +1
Measuring the photoluminescence of defects in crystals is a common experimental technique for analysis and identification. However, current theoretical simulations typically requir…
Modeling and Control of a Reconfigurable Photonic Circuit using Deep Learning
Akram Youssry, Robert J. Chapman, Alberto Peruzzo +2
The complexity of experimental quantum information processing devices is increasing rapidly, requiring new approaches to control them. In this paper, we address the problems of pra…
Quantum interference of topological states of light
Jean-Luc Tambasco, Giacomo Corrielli, Robert J. Chapman +4
Topological insulators are materials that have a gapped bulk energy spectrum, but contain protected in-gap states appearing at their surface. These states exhibit remarkable proper…
High coupling efficiency grating couplers on lithium niobate on insulator
I. Krasnokutska, R. J. Chapman, J. -L. J. Tambasco +1
We demonstrate monolithically defined grating couplers in -cut lithium niobate on insulator for efficient vertical coupling between an optical fiber and a single mode waveguide.…
Nanostructuring of LNOI for efficient edge coupling
Inna Krasnokutska, Jean-Luc J. Tambasco, Alberto Peruzzo
We present the design, fabrication and characterization of LNOI fiber-to-chip inverse tapers for efficient edge coupling. The etching characteristics of various LNOI crystal cuts a…
