An international team of scientists developed the world’s first anti-laser for a nonlinear Bose-Einstein condensate of ultracold atoms. For the first time, scientists have demonstrated that it is possible to absorb the selected signal completely, even though the nonlinear system makes it difficult to predict the wave behavior. The results can be used to manipulate…
Nano-Resonator Designed with Strong Nonlinear Response
An international research team has found a way to make light frequency conversion at the nanoscale 100 times more efficient. The new method is based on isolated dielectric nanoparticles supporting bound states in the continuum. Such states form when radiating field oscillations in the particle suppress each other. This way, the electromagnetic energy inside the…
