Chiral optical forces in a slot waveguide for separation of molecules in gas
Josep MartÃnez-Romeu, Daniel Arenas-Ortega, Iago Diez +1
Chiral optical forces present an exciting avenue into the separation of enantiomers in an all-optical fashion. In this work, we explore via numerical simulations and analytical cal…

Polarization-Insensitive Integration of Nanoparticle-on-a-Slit Cavities with Dielectric Waveguides for On-chip Surface Enhanced Raman Spectroscopy
Javier Redolat, Daniel Arenas-Ortega, Ãngela Barreda +3
Amongst the available plasmonic nanostructures, nanoparticle-on-a-mirror (NPoM) cavities - consisting of metal nanoparticles separated from a metal mirror by a molecular-size monol…

Full Silicon Pillar-based 1D Optomechanical cavities
Juliana Jaramillo-Fernandez, Martin Poblet, David Alonso-Tomás +7
Nanomechanical resonators can serve as ultrasensitive, miniaturized force probes. While vertical structures like nanopillars are ideal for this purpose, transducing their motion is…
