Caltech engineers have developed a new camera design that replaces the lenses with an ultra-thin optical phased array (OPA). The OPA does computationally what lenses do using large pieces of glass: it ...

The Astronomy and Astrophysics Decadal Survey (Astro2020) of the U.S. National Academy of Sciences has published its report and the Next Generation Very Large Array (ngVLA) received high priority for ...

Optical computing uses photons instead of electrons to perform computations, which can significantly increase the speed and energy efficiency of computations by overcoming the inherent limitations of ...

Large baselines will be required in the future to perform direct imaging and, in some cases, spectroscopic observations of exoplanets. Therefore, astronomers will inevitably be led to design large ...

In early July, we returned to the Southwest for a drive across New Mexico. During the second day, we stopped at the Karl G. Jansky Very Large Array, a huge radio telescope used by scientists to study ...

Engineers at the University of California, Berkeley have built a new photonic switch that can control the direction of light passing through optical fibers faster and more efficiently than ever. This ...

The G8921-01 gallium-arsenide (GaAs) photodiode array provides high-speed response at low bias voltage, low dark current, and low capacitance. With a four-element ...

In less than six years, Martin Valente and Jim Burge have gone from working part time in a backyard workshop to moving 22 employees into a 30,000-square-foot optics manufacturing and research facility ...

Key trends in the automotive industry involve producing safer vehicles for people inside and outside the car—smarter technology for more comfort and ease of use and toward cars that are “greener” or ...
