Hybrid Dielectric-Graphene SERS Metasurfaces for Antibody Sensing
Javier Redolat, Miguel Sinusia Lozano, María Camarena Pérez +8
We present a hybrid surface-enhanced Raman spectroscopy (SERS) platform based on dielectric silicon metasurfaces integrated with functionalized graphene for the selective detection…
Dual-mode phonon dynamics and lasing in optomechanical cavities
Raúl Ortiz, Carlos Mas Arabí, Carles Milián +1
We use the full nonlinear bifurcation theory as a powerful methodology to thoroughly classify and predict the phonon lasing dynamics in optomechanical cavities. We exemplify its sc…
Chiral optical forces in a slot waveguide for separation of molecules in gas
Josep Martínez-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…
Self-modulated multimode silicon cavity optomechanics
David Alonso-Tomás, Carlos Mas Arabí, Carles Milián +3
Multimode cavity optomechanics, where multiple mechanical degrees of freedom couple to optical cavity modes, provides a rich platform for exploring nonlinear dynamics and engineeri…
Nonlinear localized modes in Glauber-Fock photonic lattices
Alejandro J. Martínez, Uta Naether, Alexander Szameit +1
We study a nonlinear Glauber-Fock lattice and the conditions for the excitation of localized structures. We investigate the particular linear properties of these lattices, includin…
