While terahertz radiation has been generated from solids, gases, and plasmas (the "fourth state" of matter) before, no one had created terahertz light from a liquid—until now....
Researchers have broken the 1-micron bandwidth barrier by creating an integrated mid-IR waveguide Mach-Zehnder interferometer that has a 3-micron spectral operating range.
Whether cutting, welding, or patterning various materials using a laser, the materials-processing end result correlates directly with the size, shape, and intensity of the laser...
Researchers have come up with a way to create a bulk nonreciprocal mirror that, at least in theory, can have a 50 dB isolation and a very high reflection.
An infrared sensor based on a plasmonically enhanced micromechanical photoswitch remains dormant with near-zero power consumption until awakened by an external trigger or stimulus...
Amorphous silicon, with its disorder and thus abundant localized states, would be a good active material for a cycling excitation process-based low-light detector.
An optothermophoretic assembly method uses an ionic surfactant to manipulate and assemble most any colloidal matter using a light-controlled temperature field.
Physicists have theoretically determined that ultrafast laser pulses can, when focused, be made to travel at different velocities when propagating in a vacuum.
