Blue light is vital for light-emitting devices, lighting applications, as well as smartphone screens and large screen displays. However, it is challenging to develop efficient blue organic light-emitting diodes (OLEDs), owing to the high applied voltage required for their function. Conventional blue OLEDs typically require around 4 V for a luminance of 100 cd/m2. This is higher than the industrial target of 3.7…

University of Washington researchers have discovered they can detect atomic "breathing," or the mechanical vibration between two layers of atoms, by observing the type of light those atoms emitted when stimulated by a laser. The sound of this atomic "breath" could help researchers encode and transmit quantum information.

Happy 75th birthday to the transistor! Find out who was REALLY behind its invention.

Who's doing what in next-gen chips, and when they expect to do it.

We present an innovative and effective method for remote monitoring of mosquitoes and their neutralization. We explain in detail how we leverage modern advances in neural networks to use a powerful laser to neutralize mosquitoes. The experimental low-cost prototype for mosquito control, which uses a powerful laser to thermally neutralize the mosquitoes. The developed device is controlled by a single-board computer…

New generation of optical head amps deliver more speed and accuracy than fiber optic versions

This CO2, temperature and humidity sensor is so much more than just a pretty face on a slim body ...

Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. As described in Optica, Optica Publishing Group's journal for high-impact research, the new correlator is faster than other methods and works with a wide range of frequency signals, making it useful for locating cell phones, tracking tags, and more.

Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. Because the new correlator is faster than other methods and works with a wide range of radio frequency signals, it could be useful for locating cell phones, signal jammers or a variety of tracking tags.

The revolutionary Polaroid SX-70 1 camera (1972) was a marvel of engineering: the world's first instant SLR camera. This iconic camera was the brainchild of Dr. Edwin Land, a genius who co-founded Polaroid, invented polarized sunglasses, helped design the optics for the U-2 spy plane, and created a theory of color vision. The camera used self-developing film 2 with square photos that came into view over a few…

The old axiom "you get what you pay for" is often invoked in discussions of product quality. It can also inspire curiosity as to what exactly one does get when the price paid for a product is significantly less than asked by others having comparable basic specifications. It was this spirit of curiosity that led a colleague to purchase a bench-type adjustable power supply, advertising a 0-15V, 0-2A output from a…
