High-Efficiency Broadband Grating Out-Coupler for Thick Silicon Waveguides with a Tuned SiGe Layer Open
We design a novel grating out-coupler while maintaining a Gaussian-shaped far-field output. The approach is based on the patterning of a grating in a SiGe layeron the top surface of a 3-µm-thick Si waveguide. The grating aims at coupling t…

High-responsivity InSe/TaSe <sub>2</sub> photodetectors integrated on low-loss silicon nitride waveguides Open
Waveguide-integrated InSe/TaSe 2 heterostructure photodetectors exhibit high responsivity and low noise, enabled by enhanced light-matter interaction.

Temporal and spectral signatures of the interaction between ultrashort laser pulses and Bloch surface waves Open
The resonant excitation of Bloch Surface Waves (BSWs) in dielectric one-dimensional photonic crystals is becoming a realistic photonic solution for surface integration in many domains, from spectroscopy to local field management. Bringing …

Low Loss Vertical TiO2/Polymer Hybrid Nano-Waveguides Open
This article proposes a novel demonstration of a low-loss polymer channel hybridized with a titania core leading to a nano-waveguide elongated in the normal direction to the substrate. It is aimed at using the quasi-transverse magnetic (TM…

Hybrid polymer-titania waveguides for highly integrated circuits Open
We present an innovative waveguide based on the hybridization of a titanium dioxide nano-waveguide within a polymer strip. Through simulations and design we demonstrate that the waveguide sustains principally the quasi-TM fundamental mode …
