Optical detection of single sub-15 nm objects using elastic scattering strong coupling
MohammadReza Aghdaee, Oluwafemi S. Ojambati
Metallic nano-objects play crucial roles in diverse fields, including biomedical imaging, nanomedicine, spectroscopy, and photocatalysis. Nano-objects with sizes that are less than…
Few photons probe third-order nonlinear properties of nanomaterials in a plasmonic nanocavity
Anupa Kumari, MohammadReza Aghdaee, Mathis Van de Voorde +1
Quantification of nonlinear optical properties is required for nano-optical devices, but they are challenging to measure on a nanomaterial. Here, we harness enhanced optical fields…
Few-emitter lasing in single ultra-small nanocavities
Oluwafemi S. Ojambati, Kristin B. Arnardottir, Brendon W. Lovett +2
Lasers are ubiquitous for information storage, processing, communications, sensing, biological research, and medical applications [1]. To decrease their energy and materials usage,…
Breaking the Selection Rules of Spin-Forbidden Molecular Absorption in Plasmonic Nanocavities
Oluwafemi S. Ojambati, William M. Deacon, Rohit Chikkaraddy +6
Controlling absorption and emission of organic molecules is crucial for efficient light-emitting diodes, organic solar cells and single-molecule spectroscopy. Here, a new molecular…
Ultrafast long-range energy transport via light-matter coupling in organic semiconductor films
Raj Pandya, Richard Y. S. Chen, Qifei Gu +29
The formation of exciton-polaritons allows the transport of energy over hundreds of nanometres at velocities up to 10^6 m s^-1 in organic semiconductors films in the absence of ext…
Three-dimensional photonic band gap cavity with finite support: enhanced energy density and optical absorption
D. Devashish, Oluwafemi Ojambati, Shakeeb B. Hasan +2
We study numerically the transport and storage of light in a 3D photonic band gap crystal doped by a single embedded resonant cavity. The crystal has finite support since it is sur…
3D spatially-resolved optical energy density enhanced by wavefront shaping
Peilong Hong, Oluwafemi S. Ojambati, Ad Lagendijk +2
We study the three-dimensional (3D) spatially-resolved distribution of the energy density of light in a 3D scattering medium upon the excitation of open transmission channels. The…
Non-Rayleigh distribution of reflected intensity from photonic crystals with disorder
Oluwafemi S. Ojambati, Elahe Yeganegi, Ad Lagendijk +2
Structural disorder results in multiple scattering in real photonic crystals, which have been widely used for applications and studied for fundamental interests. The interaction of…
Controlling the intensity of light in large areas at the interfaces of a scattering medium
Oluwafemi S. Ojambati, John T. Hosmer-Quint, Klaas-Jan Gorter +2
The recent advent of wave-shaping methods has demonstrated the focusing of light through and inside even the most strongly scattering materials. Typically in wavefront shaping, lig…
Energy density distribution of shaped waves inside scattering media mapped onto a complete set of diffusion modes
Oluwafemi S. Ojambati, Allard P. Mosk, Ivo M. Vellekoop +2
We show that the spatial distribution of the energy density of optimally shaped waves inside a scattering medium can be described by considering only a few of the lowest eigenfunct…
Selective coupling of optical energy into the fundamental diffusion mode of a scattering medium
Oluwafemi S. Ojambati, Hasan Yilmaz, Ad Lagendijk +2
We demonstrate experimentally that optical wavefront shaping selectively couples light into the fundamental diffusion mode of a scattering medium. The total energy density inside a…
