How Far Down the Road Is the Autonomous Vehicle?
How Far Down the Road Is the Autonomous Vehicle?
Designers have learned how difficult it is to resolve those last couple of percentage points before any design meets the target specifications for a project. Autonomous vehicle (AV) technology is truly in the “last mile” of development, but like for many design projects, that mile can take the majority of the development time. In the case of autonomous vehicles, the last mile involves the challenges of capturing sufficient quality data, enabling the AV system to make good decisions, and resolving the corner cases — the problems or situations that occur outside of normal operating parameters.

Ultrafast Lasers Are Quickly Catching Up with Industry Demand
Ultrafast Lasers Are Quickly Catching Up with Industry Demand
With pulse lengths down to the picosecond realm and beyond, ultrashort-pulse lasers — often called ultrafast lasers — have been deployed as scientific research tools for decades. The fields of femtochemistry, spectroscopy, and multiphoton imaging, in particular, have benefited from the technology, which has since enabled new investigations in neuroscience and quantum mechanics. Now, however, ultrafast lasers are starting to expand beyond their traditional research niche.

Managing Temperature-Based Performance Drift for Coatings
Managing Temperature-Based Performance Drift for Coatings
What happens when optical coatings get very cold? There should be little difference in a thin film’s optical performance at room temperature test conditions versus its use conditions. But this is not always the case. Performance varies at different temperatures, and systems engineers, program managers, and other stakeholders must account for when and where these coating performance differences occur to realize ideal instrument performance.

Laser Pulses Trigger Ultrafast Material Property Shift
Laser Pulses Trigger Ultrafast Material Property Shift
Researchers from the Fritz Haber Institute of the Max Planck Society and the Max Planck Institute for the Structure and Dynamics of Matter demonstrated the ability to use light to achieve a novel type of ultrafast switch. The efforts stem from the collaborators’ pursuit of ever-increasing speed in electronics and computing technologies. Transistors that turn electrical currents on and off quickly are pillars of those technologies.

Organic Electrochromic Material Changes Colors Rapidly, Reversibly
Ludwig-Maximilians-Universität researchers developed an electrochromic thin-film material that, by changing colors rapidly, is poised to feature in the design of smart windows, solar energy production/acquisition, and automotive applications. The material, which relies on electricity to change colors, is part of a generation of highly ordered lattice structures, known as covalent organic frameworks. These are made up of synthetically conceived organic building blocks that, under the right conditions, form crystalline and nanoporous networks.

Synapse-Like Phototransistor Enables Persistent, Low-Energy Optical Switching
Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) created a phototransistor that allows long-lived persistent photoconductivity (PPC), which is a form of optical memory. The new structure is a heterojunction between perovskite semiconductors and carbon nanotubes. The device could enable optical switching with low energy consumption for potential use in sensors and artificial neural networks and in applications such as self-driving vehicles.
