To make silicon photonics devices profitably at scale, automation subsystems require alignment processes that support steps from device characterization at the wafer level to ...

In less than a decade, femtosecond laser-assisted cataract surgery has gone from hotly anticipated to coolly considered. Now, developers are addressing the barriers, while the...
Replacing free-space optics with fiber-coupled, integrated components allows modular terahertz time-domain imaging systems to excel in solar and semiconductor wafer analysis.
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.
