The arrows indicate the direction in which the light travels, and the size of the cylinder indicates the intensity of the light. The intensity of light transmitted through a magnetic material (the ...

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 ...

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 ...

A Japanese collaboration dominated by engineers from Meijo University claims to have delivered significant advances in the ...

Santa Clara, CA and Kyoto, Japan, Oct. 07, 2021 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced they have developed a high optical output laser diode, the RLD90QZW3, for applications such as ...

TOKYO--(BUSINESS WIRE)--Mitsubishi Electric Corporation (TOKYO:6503) announced today that it will begin shipping samples of its new tunable laser-diode chip for use in optical transceivers of ...

WEST LAFAYETTE, Ind. - 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 ...

The problem is efficiency. Maxwell's equations are completely linear, so nonlinear optics relies entirely on materials with nonlinear response to optical fields. Unfortunately these responses deviate ...

Osaka, Japan – At the heart of global internet connectivity, optical communications form an indispensable foundation. Key to this foundation are optical isolators, created by combining multiple ...
