Optical frequency combs with a new dimension

Periodic pulses of light forming a comb in the frequency domain are widely used for sensing and ranging. The key to the miniaturization of this technology toward chip-integrated solutions is the generation of dissipative ...

Scientists prevent critical collapse of higher-order solitons

Solitons are stable objects balanced by diffraction or dispersion and nonlinearity. A fundamental challenge in this field is the stabilization of solitons in multidimensional coordinates, since the 2-D and 3-D solitons in ...

Schools of molecular 'fish' could improve display screens

Take a dive into what may be the world's smallest coral reef. Scientists at the University of Colorado Boulder are using a type of material called liquid crystals to create incredibly small, swirling schools of "fish," according ...
