Enhanced excitation and readout of plasmonic cavity modes in NPoM via SiN waveguides for on-chip SERS
J. Enrique Vázquez-Lozano, Jeremy J. Baumberg, Alejandro Martínez
Metallic nanoparticle-on-a-mirror (NPoM) cavities enable extreme field confinement in sub-nm gaps, leading to unrivaled performance for nonlinear processes such as surface-enhanced…
Hybrid Photonic-Plasmonic Cavities based on the Nanoparticle-on-a-Mirror Configuration
Angela I. Barreda, Mario Zapata-Herrera, Isabelle Palstra +4
Hybrid photonic-plasmonic cavities have emerged as a new platform to increase light-matter interaction capable to enhance the Purcell factor in a singular way not attainable with e…
Floquet phonon lasing in multimode optomechanical systems
Laura Mercadé, Karl Pelka, Roel Burgwal +3
Dynamical radiation pressure effects in cavity optomechanical systems give rise to self-sustained oscillations or `phonon lasing' behavior, producing stable oscillators up to GHz f…
Vertical engineering for large stimulated Brillouin scattering in unreleased silicon-based waveguides
Laura Mercadé, Alexander V. Korovin, Yan Pennec +2
Strong acousto-optic interaction in silicon-based waveguides generally requires releasing of the silicon core to avoid mechanical leakage into the underlying silica substrate. This…
Towards Chiral Sensing and Spectroscopy Enabled by All-Dielectric Integrated Photonic Waveguides
J. Enrique Vázquez-Lozano, Alejandro Martínez
Chiral spectroscopy is a powerful technique that enables to identify the chirality of matter through optical means. So far, experiments to check the chirality of matter or nanostru…
Near-Field Directionality Beyond the Dipole Approximation: Electric Quadrupole and Higher-Order Multipole Angular Spectra
J. Enrique Vázquez-Lozano, Alejandro Martínez, Francisco J. Rodríguez-Fortuño
Within the context of spin-related optical phenomena, the near-field directionality is generally understood from the quantum spin Hall effect of light, according to which the trans…
Nonlinear Excitations in Magnetic Lattices with Long-Range Interactions
Miguel Molerón, C. Chong, Alejandro J. Martínez +3
We study - experimentally, theoretically, and numerically - nonlinear excitations in lattices of magnets with long-range interactions. We examine breather solutions, which are spat…
Classical Emergence of Intrinsic Spin-Orbit Interaction of Light at the Nanoscale
J. Enrique Vázquez-Lozano, Alejandro Martínez
Traditionally, in macroscopic geometrical optics intrinsic polarization and spatial degrees of freedom of light can be treated independently. However, at the subwavelength scale th…
Lateral forces on nanoparticles near a surface under circularly-polarized plane-wave illumination
Francisco J. Rodríguez-Fortuño, Alejandro Martínez, Nader Engheta +1
Optical forces allow manipulation of small particles and control of nanophotonic structures with light beams. Here, we describe a counter-intuitive lateral optical force acting on…
Spatial storage of discrete dark solitons
Alejandro J. Martínez, Yair Zárate
The interaction between a mobile discrete dark soliton (DDS) and impurities in one-dimensional nonlinear (Kerr) photonic lattices is studied. We found that the scattering is an ine…
Nonlinear multi-core waveguiding structures with balanced gain and loss
Alejandro J. Martínez, Mario I. Molina, Sergei K. Turitsyn +1
We study existence, stability, and dynamics of linear and nonlinear stationary modes propagating in radially symmetric multi-core waveguides with balanced gain and loss. We demonst…
Regarding the "Comments on 'Near-field interference for the unidirectional excitation of electromagnetic guided modes' " by Lee et al
Francisco J. Rodríguez-Fortuño, Giuseppe Marino, Pavel Ginzburg +4
We would like to clarify the misunderstanding caused by comment [arXiv:1306.5068 (2013)] on our article [Science 340, 328 (2013)]. The vectorial near-field interference effect desc…
