Laser Switched Optical Transistor Could Enable future generation of ultrafast light-based computers

by

An artist’s impression of a molecule acting as a transistor that makes it possible to use one laser beam to tune the power of another (Image: Robert Lettow) An optical transistor that uses one laser beam to control another could form the heart of a future generation of ultrafast light-based computers, say Swiss researchers. Conventional …

Lasers Can Create Temporal Lens of Attosecond Electron Pulses for Molecular Movies

by

A team at the University of Nebraska-Lincoln has figured out a possible way to observe and record the behavior of matter at the molecular level. That ability could open the door to a wide range of applications in ultrafast electron microscopy used in a large array of scientific, medical and technological fields. The “lenses” in …

Carbon Nanotube Quantum Dot Terahertz Detectors and On-Chip High Resolution near-field terahertz detector

by

Two types of emerging terahertz detectors are based on novel nanoelectronic technologies. Future work to combine the two will enable a real time terahertz video camera. 1. A highly sensitive and frequency tunable terahertz detector based on a carbon nanotube (CNT) quantum dot (QD). Observations have been made of electron tunneling via terahertz-photon detection, called …

Progress in Understanding Regeneration in Salamanders

by

Shwann cells are shown here in a salamander limb. When the limb regrew after being amputated, only these cells wrapped around nerve fibers; other cell types did not turn into Shwann cells. Credit: D. Knapp/E. Tanaka The salamander is a superhero of regeneration, able to replace lost limbs, damaged lungs, sliced spinal cord — even …
