2D Material Takes on Chirality of Circularly Polarized Light
CAMBRIDGE, Mass., March 2, 2020 — 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 (TiSe2), is a...
OFC 2020 Celebrates 50 Years of Light-Speed Connections
SAN DIEGO, March 2, 2020 — The Optical Networking and Communication Conference & Exhibition (OFC 2020), to be held at the San Diego Convention Center March 8-12, celebrates the 50th anniversary of the first viable optical fiber. The world’s largest conference on...
Materials Integrated with Silicon Photonics Manipulate Light Phase at Low Loss
NEW YORK, March 2, 2020 — A Columbia University team used a 2D material from the transition metal dichalcogenide (TMD) class to control the phase of light without changing its amplitude or depleting its power. By placing the atomically thin material on top of passive silicon...
High-Pulse-Energy Air-Cooled Lasers
Mar 2, 2020 — Size, weight, and power (SWaP) are key attributes of laser transmitters for military, defense, and aerospace applications. Battlefield lasers must be compact, lightweight, and have high wall-plug efficiencies to meet aggressive demands. Fiber lasers...
IPG Photonics Posts Modest Growth in 2019 Net Revenue
OXFORD, Mass., March 2, 2020 — IPG Photonics Corp. financial results for the fourth quarter of 2019, announced in mid-February, showed that fourth-quarter 2019 net income was a loss of $4 million, which included goodwill and asset impairment, inventory provision and restructuring...
Edmund Optics Opens Bangalore Office
BARRINGTON, N.J., March 2, 2020 — Edmund Optics (EO) has opened a new office in the Bangalore district of Karnataka, India, with a full-service website and technical support from local engineers. The company has conducted business in India for over a decade through the support of...
Lasers for Hybrid Silicon Photonic Integration
Feb 28, 2020 — The wide adoption of smartphones, high-definition content streamed on social media, the Internet of Things, data saved to the cloud, and artificial intelligence used in massive data analytics have ushered in the current era of digital economies and...
Researchers Demonstrate 3-Photon Split in the Microwave Domain
WATERLOO, Ontario, Feb. 28, 2020 — Researchers at the University of Waterloo have directly split one photon into three. To do so, they created a non-Gaussian state of light using spontaneous parametric down-conversion (SPDC). Traditional SPDC, which splits a high-energy pump photon...
Technique Interprets Hyperspectral Images Using Phasor Approach
LOS ANGELES, Feb. 28, 2020 — An imaging technique called spectrally encoded enhanced representations (SEER) provides greater clarity and works up to 67 times faster and at 2.7 times greater definition than existing spectral imaging techniques, according to its developers at the...
Organic Nanomaterials and Metal Particles Could Mean Better Batteries
BUSAN, South Korea, Feb. 28, 2020 — Researchers from the National Korea Maritime and Ocean University have developed a method for adding metals to organic materials that they claim is simple, safe, and cost-effective. The method will allow the production of sodium-ion batteries, an...
Researchers Develop Method to Dramatically Reduce Imaging Noise
HOBOKEN, N.J., Feb. 27, 2020 — Researchers at Stevens Institute of Technology created a 3D imaging system that uses light’s quantum properties to create images 40,000 times crisper than current technologies. The research could allow for better lidar sensing and detection,...
