Light-Intensity Switching of Graphene/WSe2 Synaptic Devices
Giulia Tagliabue, Tarique Anwar, Hongyu Tang
2D van der Waals heterojunctions (vdWH) have emerged as an attractive platform for the realization of optoelectronic synaptic devices, which are critical for energy-efficient computing systems. Photogating induced by charge traps at the interfaces indeed r ...
Wiley2024Strain engineering and strain measurement by spring tethers on suspended epitaxial GaN-on-Si photonic crystal devices
Suspended epitaxial gallium nitride (GaN) on silicon (Si) photonic crystal devices suffer from large residual tensile strain, especially for long waveguides, because fine structures tend to crack due to large stress. By introducing spring-like tethers, des ...
Bristol2024Exciton migration in two-dimensional materials
Excitons play an essential role in the optical response of two-dimensional materials. These are bound states showing up in the band gaps of many-body systems and are conceived as quasiparticles formed by an electron and a hole. By performing real-time simu ...
Nature Portfolio2024Parametric Wavelength Conversion in Waveguiding Structures: Efficiency, Bandwidth and Polarization
Photonics integrated circuits are a promising solution for the growing demands of data transmission and future system-on-chip technologies. Within this context, nonlinear optical interactions offer unique opportunities for all-optical processing, sampling, ...
EPFL2024Fully reconfigurable MEMS-based second-order coupled-resonator optical waveguide (CROW) with ultra-low tuning energy
Niels Quack, Alain Yuji Takabayashi
Integrated microring resonators are well suited for wavelength-filtering applications in optical signal processing, and cascaded microring resonators allow flexible filter design in coupledresonator optical waveguide (CROW) configurations. However, the imp ...
Washington2023Polariton lasing in AlGaN microring with GaN/AlGaN quantum wells
Nicolas Grandjean, Jean-François Carlin, Raphaël Butté
Microcavity polaritons are strongly interacting hybrid light-matter quasiparticles, which are promising for the development of novel light sources and active photonic devices. Here, we report polariton lasing in the UV spectral range in microring resonator ...
AIP Publishing2023Domain Imaging and Switching Dynamics in BaTiO3-Based Photonic Integrated Devices
Keeping up with our constantly connected lifestyle of instant messages and video streaming has its repercussions. Data centers have been gobbling up resources becoming a significant share of the energy used worldwide. To keep up with demand and curb the en ...
