TL;DR: In this article, the use of chalcogenide glass, a multifunctional material that can be directly deposited and patterned on a wide variety of 2D materials and can simultaneously function as the light-guiding medium, a gate dielectric and a passivation layer for 2D material.

TL;DR: In this paper, the authors quantitatively compare the sensing performance of various waveguide geometries through figures of merit that derive for each mode of sensing, taking into account both modal confinement and roughness scattering loss, the latter of which is computed using a volumecurrent (Green's-function) method with a first Born approximation.

TL;DR: In this article, an approach to monolithically fabricate photonic devices on 2D materials including graphene was developed and demonstrated its significant potential for high-performance photonic integration.

TL;DR: In this paper, the authors use chalcogenide glass, a multifunctional material which can be directly deposited and patterned on a wide variety of 2D materials and can simultaneously function as the light guiding medium, a gate dielectric, and a passivation layer for 2-D materials, and demonstrate a series of high-performance glass-on-graphene devices including ultra-broadband on-chip polarizers, energy-efficient thermo-optic switches, as well as graphene-based mid-infrared (mid-IR) wave
