A micrometer-sized liquid crystal droplet doped with fluorescent dye functions as a nanosecond optical switch that controls light output using light alone. The resonant cavity design cuts the energy ...

Controlling light with light is a long-sought goal for computing and communication technologies. Achieving this capability would allow optical signals to be processed without converting them into ...

NYU researchers have found a way to use light to control how microscopic particles assemble into crystals, effectively ...

A research team at POSTECH has developed a method for synthesizing perovskite nanocrystals (PNCs), a next-generation semiconductor material, in a more uniform and efficient manner. This study is ...

Spontaneous parametric down-conversion (SPDC), as a source of entangled photons, is of great interest for quantum physics and quantum technology, but so far it could be only implemented in solids.

The best candidate for next-generation magnetic devices—technology that can power, store, sense or transport information—may be, counterintuitively, antiferromagnets. Today, the most widely used ...

Creating quantum light just became easier thanks to liquid crystals like the ones found in television screens. Team member Vitaliy Sultanov at the Max Planck Institute for the Science of Light in ...

Any device that can control or change the amplitude, phase, or polarization of light waves is known as a Spatial Light Modulator (SLM). “Current SLM–based systems use either optical MEMS ...

(Nanowerk Spotlight) Color plays a crucial role in our daily lives, from the clothes we wear to the screens we gaze at. Yet, traditional methods of creating color, which rely on chemical pigments and ...
