Photonic Technologies Energize Sustainability
It could be a greener world, thanks to photonic technologies. That’s the conclusion of a 2020 study forecasting that photonics could eliminate 3 billion tons of CO2 emissions annually by 2030.

All-Optical Switching Alternatives for Data Processing
For decades, computer technology has steadily achieved astonishing gains in performance, but it is becoming increasingly unclear how much longer this rapid progress can continue without considerable technological innovation.

Optical Materials Bending the Rules, Shaping Our World
From the emergence of diverse 2D materials (perovskites for efficient solar cells) and twisted bilayer graphene (superconductive at a “magic angle”) to the boom in polymer science and the promise of quantum photonics, materials science is rapidly evolving.

2D Material Takes on Chirality of Circularly Polarized Light
Physicists at MIT have uncovered a new way to test whether or not a material is chiral, and have also found a way to enhance the overall chirality in a large piece of material. The material they used, titanium diselenide, is a transition-metal dichalcogenide semimetal that has potential use in quantum devices.

Until now, a complex experimental setup was required to measure the shape of a laser lightwave with a high degree of accuracy. This measurement can now be done using a small crystal with a diameter of less than 1 mm. The new method uses extremely short pulses, with a duration in the order of femtoseconds.

Scientists at the University of California, Berkeley, have created a blue light-emitting diode from halide perovskite, a new semiconductor material said to be cheap and easy to manufacture, overcoming a barrier that had previously prevented the employment of the devices. However, in the process, the team also discovered a fundamental property of halide perovskites that may prove a barrier to their widespread use as solar cells and transistors.

Beam Shaping: The Next Step for Ultrashort-Pulse-Laser-Based Processes
Thu, Jul 16, 2020 10:00 AM - 11:00 AM EDT
The use of ultrashort pulse (USP) lasers in industrial processes is growing, thanks to the high standard of quality that can be achieved. For widespread industrial use of USP lasers to be realized, however, two key challenges need to be solved: The yield has to strongly increase for the process to be cost-effective, and improvement in quality will lead to the processing of new materials and the development of new markets. This webinar will present how beam shaping can solve these two challenges, and how multi-plane light conversion (MPLC) can achieve yield and quality improvement while being compatible with industrial setups.
