High Fidelity Waveguides Through Vitreous Media Recomposition for Next Generation Photonic Devices

open access: yesAdvanced Optical Materials, EarlyView.
A newly designed aluminosilicate glass enables the fabrication of femtosecond laser‐written optical waveguides with ultra‐low propagation losses of −0.020 dB cm−1 at 1310 nm and −0.037 dB cm−1 at 1550 nm. Raman, Brillouin, and electron microscopy analyses reveal the mechanisms behind refractive index modifications, highlighting the role of glass ...

Parallelizing pairings on Hessian elliptic curves

open access: yesArab Journal of Mathematical Sciences, 2019
This paper considers the computation of the Ate pairing on the Hessian model of elliptic curves. Due to the many important properties making the model attractive in cryptography, we compute for the first time the Ate pairing on this model and show how ...

Toward Direct Laser Writing of Dual‐Layer Metasurfaces with the Plasmonic Phase‐Change Material In3SbTe2

open access: yesAdvanced Optical Materials, EarlyView.
A simple optical programming technique is developed for fabricating plasmonic nanoantennas in a dual‐layer metasurface by crystallizing the plasmonic phase‐change material In3SbTe2 from the top and through the substrate with a subsequent reamorphization step.

An efficient method to generate elliptic curves

open access: yesTongxin xuebao, 2001
In this paper, an efficient method to generate elliptic curves for public key cryptosystems based on discrete logarithm problem is presented. Usually, to resist possible attacks, such as MOV reduction, public key cryptosystems based on elliptic curve E ...

Large Electrogyration Effect in Ferroaxial NiTiO3 at Near Infrared Wavelengths

open access: yesAdvanced Optical Materials, EarlyView.
A large electrogyration effect (electric field‐induced optical rotation) is observed in a ferroaxial crystal NiTiO3 at near infrared wavelengths. The Ni2+ d‐d transitions, featuring strong magnetic dipole character, play an important role in producing the pronounced effect.

Differential operators over particular elliptic curves spaces with cryptographic applications

open access: yesElectronic Journal of Differential Equations, 2015
Finding optimal implementations to solve differential equations in the case of boundary conditions is an open problem. In the particular case of using nonsupersingular elliptic curves there are applications in the asymmetric encryption field ...
