The passive optical diode developed at Purdue makes this possible with light instead of electrons. The new diode is made from two silicon rings that measure just 10 microns in diameter, which is ...

The “passive optical diode” is made from two tiny silicon rings measuring 10 microns in diameter, or about one-tenth the width of a human hair. Unlike other optical diodes, it does not require ...

A group of researchers from the Washington University of St. Louis (WUSTL) have managed to create the first optical diode. In theory, an optical diode performs a very simple task. Photons coming ...

In his endless quest for more optical power ... module along with a function generator to provide the pulses. The driver was able to push 80 amps into a Nichia NUBM47 diode for just a few ...

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 ...

A Los Alamos National Laboratory team has overcome key challenges toward technologically viable high-intensity light emitters based on colloidal quantum dot technology, resulting in dual-function ...

referred to as the optical diode effect, in which divalent nickel (Ni2+) ions are responsible for magnetism, by passing light at shortwave infrared wavelengths used in optical communications.

write and rewrite times for optical recording. National's LMH6533 laser diode driver contains two high-current outputs for reading and writing DVD (650nm) or CD (780nm) lasers. It achieves read, write ...

Engineers at the UCLA Samueli School of Engineering have introduced a universal framework for point spread function (PSF) engineering, enabling the synthesis of arbitrary, spatially varying 3D PSFs ...
