Image showing gold contacts where we bias each laser with DC current. Light is out-coupled from the racetracks using the directional-coupler waveguides along the straight section of either racetrack.

Physicists are now using a tightly controlled laser and a cloud of ultracold atoms to imitate the behavior of electrons in solids, effectively building a quantum version of electronics out of light ...

[The Thought Emporium] has been fascinated by holograms for a long time, and in all sorts of different ways. His ultimate goal right now is to work up to creating holograms using chocolate, but along ...

A patent application (Publication Number: US20230391125A1) describes a method for creating finishing patterns on garments using a laser. The method involves providing an assembled garment made from ...

A new laser-based technique has revealed the intricate details of tattoos on centuries-old mummies in Peru, archaeologists report in a new study. However, not everyone is convinced that the new ...

A scalable nanofabrication method uses electric-field alignment and picosecond laser welding to imprint patterned silver ...

Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom ...
