Guided-mode resonance filters (GMRFs) and cavity resonators represent a transformative class of optical devices that exploit the resonant coupling between incident light and leaky modes in dielectric ...

Scientists have found a clever way to supercharge ultra-thin semiconductors by reshaping the space beneath them rather than ...

Electro-optical and photonic devices have made great progress in their level of integration and performance. However, they do ...

Electron-phonon scattering is often the primary mechanism limiting electron mobility in semiconductors. Thus, changing phonon properties can provide a way to control conductivity. Recently, there has ...

Gallium nitride (GaN)-based vertical-cavity surface-emitting lasers (VCSELs) are a type of semiconductor laser diode that have potential applications in many areas, including adaptive headlights, ...

Optical cavities, also known as optical resonators, are structures that confine light within a small volume by utilizing highly reflective surfaces. These cavities allow light to circulate or bounce ...

Using a standard CMOS process, researchers have combined acoustic MEMS and other technology to create a >10-GHz on-chip resonator function for filters and VCOs. How standard CMOS process can be used ...

A research team led by Pasquale Scarlino at EPFL has built a small, tunable detector capable of sensing individual microwave ...
