Green-Graphene protective overlayer on optical microfibers: pro-longs the device lifetime
A. Novikova, A. Katiyi, A. Halstuch +1
Optical microfibers finds new applications in various fields of industry, which in turn requires wear resistance, environmental friendliness and ease of use. However, optical micro…
On-chip beam rotators, adiabatic mode converters, and waveplates through low-loss waveguides with variable cross-sections
Bangshan Sun, Fyodor Morozko, Patrick S. Salter +14
Photonics integrated circuitry would benefit considerably from the ability to arbitrarily control waveguide cross-sections with high precision and low loss, in order to provide mor…
Super-resolution imaging and optomechanical manipulation using optical nanojet for non-destructive single-cell research
Alina Karabchevsky, Tal Elbaz, Aviad Katiyi +2
Advanced photonic tools may enable researchers and clinicians to visualize, track, control and manipulate biological processes at the single-cell level in space and time. Biologica…
Green-extraction of carbon thin films from natural mineral Shungite
Anastasia Novikova, Alina Karabchevsky
Conventional fabrication methods to produce graphene are cumbersome, expensive and are not ecology friendly. This is due to the fact that a large volume of raw materials requires a…
TiCT MXene Enabled All-Optical Nonlinear Activation Function for On-Chip Photonic Deep Neural Networks
Adir Hazan, Barak Ratzker, Danzhen Zhang +5
Neural networks are one of the first major milestones in developing artificial intelligence systems. The utilisation of integrated photonics in neural networks offers a promising a…
Purcell effect in PT-symmetric waveguides
Alina Karabchevsky, Andrey Novitsky, Fyodor Morozko
This chapter overviews the principles of the spontaneous emission rate increase, that is the Purcell effect, in relation to the photonic parity-time (PT) symmetry. Being focused on…
