A research group has discovered significant nonreciprocal optical absorption of LiNiPO4, referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by ...

The world's first automatic and adaptive, dual-mode light-emitting diode (LED)-based optical wireless power transmission ...

The Massachusetts Institute of Technologyrecently demonstrated a thinfilmoptical diode that designers canintegrate onto a silicon photonic chip alongwith lasers and waveguides. This task ...

(Nanowerk News) Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers ...

(Phys.org) -- Light-emitting diodes at infrared wavelengths are the magic behind such things as night vision and optical communications, including the streaming data that comes through Netflix.

High power red laser diodes are a critical building block for laser TV and display applications. New projectors require several 10s of Watts of combined red, green and blue laser optical power to meet ...

It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave ...

(Nanowerk News) At the heart of global internet connectivity, optical communications form an indispensable foundation. Key to this foundation are optical isolators, created by combining multiple ...

Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC ...
