The past few decades have seen astonishing advances in imaging technology, from high-speed optical sensors that process over two million frames per second to tiny lensless cameras that record images using a single pixel.
Radar altimeters are the sole indicators of altitude above a terrain. Spectrally adjacent 5G cellular bands pose significant risks of jamming altimeters and impacting flight landing and takeoff. As wireless technology expands ...
Similar to electronics, photonic circuits can be miniaturized onto a chip, leading to a so-called photonic integrated circuit (PIC). Although these developments are more recent than for electronics, this field is rapidly ...
Researchers report December 5 in the journal Neuron that mice display behavior that resembles self-recognition when they see themselves in the mirror. When the researchers marked the foreheads of black-furred mice with a ...
Researchers at the University of Sydney Nano Institute have invented a compact silicon semiconductor chip that integrates electronics with photonic, or light, components. The new technology significantly expands radio-frequency ...
Photonic integrated circuits (PICs) are compact devices that combine multiple optical components on a single chip. They have a wide range of applications in communications, ranging, sensing, computing, spectroscopy, and quantum ...
A research team led by Professor Sei Kwang Hahn and Dr. Tae Yeon Kim from the Department of Materials Science and Engineering at Pohang University of Science and Technology (POSTECH) used gold nanowires to develop an integrated ...
With the explosive growth of data traffic, it is highly desired to develop hybrid photonic integrated circuits combining various optical components on a single chip.
With the growth in artificial intelligence (AI), 5G systems, cloud computation, and the Internet of Things, transmitters with extremely high capacities are required for data communication. Ultrafast optical modulation is ...
Researchers have developed an easy-to-use optical chip that can configure itself to achieve various functions. The positive real-valued matrix computation they have achieved gives the chip the potential to be used in applications ...
