Opaque materials can transmit light when excited by a high-intensity laser beam. This process, known as optical bleaching, induces a nonlinear effect that temporarily alters the properties of a ...

Over the past decades, engineers have introduced numerous technologies that rely on light and its underlying characteristics. These include photonic and quantum systems that could advance imaging, ...

A nanostructure made of silver and an atomically thin semiconductor layer can be turned into an ultrafast switching mirror device that may function as an optical transistor—with a switching speed ...

The physical interaction between two or more systems, also known as coupling, can give rise to unique and unexpected effects. In the field of optics, coupled light sources (e.g., lasers) can influence ...

Applied Materials has launched a new generation of optical semiconductor wafer inspection machines that incorporate big data and AI techniques. These multimillion-dollar machines are used in chip ...

Using complex experimental set-ups, the researchers study the extremely fast movements of electrons in solids with laser pulses with a high degree of temporal resolution. A nanostructure made of ...
