But in the not-so-distant past, the tech world relied on wires, not just to power things but to connect them to output devices — wires like the optical audio cable. Optical audio uses fiber ...

However, harnessing these waves has proven exceptionally difficult. Current methods require complex combinations of electrical, thermal, and optical controls, making devices bulky and slow to respond.

A new "lensless" device could help, as it uses light to instantly detect harmful microorganisms. Usually, in order to check drinking water for bacteria, a sample of that water must be cultured in ...

As smartphone sales plateau compared to the rapid growth seen 5-10 years ago, Taiwan's optical solutions providers, primarily serving the smartphone market, are seeking new growth engines ...

These light source devices will be applied to the transmission part of optical transceivers (optical transmitter and receiver modules), essentially being inserted into the line cards within the ...

Therefore, it is imperative to implement robust encryption and authentication mechanisms within wearable devices. Herein, we suggest a flexible and wearable encryption primitive based on an optical ...

(Nanowerk News) When we last checked in with Caltech's Kerry Vahala three years ago, his lab had recently reported the development of a new optical device called a turnkey frequency microcomb that has ...
