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 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.

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 ...

Santa Clara, CA — National Semiconductor launches its newest laser diode driver (LDD) for use in optical pickup units (OPUs). The LMH6533 has extremely fast switching rates and very low output current ...

(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 ...
