This manuscript puts forward and verifies an analytical approach for the design of phononic crystals that feature a bandgap at the lowest possible frequencies, in the sense of finding the optimal layer thicknesses for a given set of materials in a prescrib ...
This paper explores the design and optimization of all-dielectric metasurfaces, consisting of silicon meta-atoms on calcium fluoride (CaF2) and silicon nitride (Si3N4) substrates, to enhance infrared absorption. This optimization results in intense light-m ...

Double-negative refractive index materials have attracted sustained experimental and theoretical interest because they can display a range of surprising optical phenomena, including negative Doppler shifts and perfect lensing. Double-negative indexes have ...
We design high-Q metasurfaces with resonant wavelengths in mid-IR varying continuously along the sample. We demonstrate tunable rainbow generation of high harmonics as we vary the pump wavelength and the coordinate along the metasurface. ...
Coherent optomechanical interaction known as stimulated Brillouin scattering (SBS) can enable ultrahigh resolution signal processing and narrow-linewidth lasers. SBS has recently been studied extensively in integrated waveguides; however, many implementati ...
Guiding and confining light at interfaces is crucial for applications involving light-matter interactions, such as surface spectroscopy, nonlinear optics, and quantum information technology. While dielectric surface waves offer promising perspectives for s ...
We present our work to extend silicon photonics with MEMS actuators to enable low-power, large scale programmable photonic circuits. For this, we start from the existing iSiPP50G silicon photonics platform of IMEC, where we add free-standing movable wavegu ...
Textile electronics embedded in clothing represent an exciting new frontier for modern healthcare and communication systems. Fundamental to the development of these textile electronics is the development of the fibers forming the cloths into electronic dev ...
