Conventional spontaneous Raman spectroscopy of interfacial molecules typically requires plasmonic or electronic enhancement, limiting accessible systems. A nonlinear coherent Raman method now enables direct, high sensitivity ...
Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device footprint. The development ...
Today, I want to walk you through a deceptively simple innovation from the lab at Loughborough University (PI: Prof Marco Peccianti): what happens when we decorate a spintronic heterostructure with a sparse layer of plasmonic ...
Light, as we usually conceive of it, is defined by the astonishing velocity at which it moves from one point to another. For example, in just one second, light can travel most of the distance between Earth and the moon. This ...
Tiny robots—around 50 times smaller than the diameter of a human hair—open up fascinating possibilities: they enable the controlled manipulation of objects far too small for human hands. This brings us closer to a long-standing ...
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field rotates. The other comes from the shape of the wavefront itself, which can twist like a corkscrew ...
Recent advancements in nanophotonics are moving beyond isotropic noble metals to achieve dynamic and directional control over plasmons. Conventional localized surface plasmon resonances (LSPR) are limited by their isotropic ...
Argonne and Northwestern University scientists teamed up to understand how light interacts with metallic nanoframes, with implications for biosensing, quantum information science and beyond.
Just as an antenna interacts with radio waves, light interacts with metallic nanostructures. Therefore, understanding how a structure influences field oscillations provides valuable insights into the structure's physical ...
Scientists have created the first microlasers capable of detecting individual molecules and even single atomic ions, a breakthrough that could significantly advance early disease diagnosis and molecular-scale medical testing. ...
