The integration of transition metal dichalcogenide layers into photonic devices is a current challenge in the field of 2D materials. Based on numerical simulations, this work explores the design of devices combining an MoS _2 monolayer with planar ph

The authors numerically analyse the performance of a mesoscopic photonic crystal (MPhC) waveguide that could be exploited to develop a new class of routing elements and a cascadable circuitry taking advantage of the spatial and spectral reconfigurabi

We theoretically demonstrate a mid-infrared polarization-independent guided-mode-resonance transmission filter. We designed a structure based on a deeply-etched 2D grating above a thin slab of the same material respectively supporting transverse magn

Active suspended membranes are an ideal test-bench for experimenting with novel laser geometries and principles. We show that adding thin AlGaAs barrier near the top and bottom Air/GaAs interfaces of the membrane significantly reduces the carriers no

We report on the design of cavity-resonator integrated grating couplers for second-harmonic generation. The key point is that the base pattern of our grating coupler (GC) is made of two ridges with different widths (bi-atom). Thus, we reach extremely

In this paper, dielectric Cavity-Resonant Integrated-Grating Filters (CRIGFs) are numerically optimized to achieve extremely high-quality factors, by optimizing the cavity in/out-coupling rate and by introducing apodizing mode-matching sections to re
