Observing distant objects is no easy task, thanks to our planet's thick and fluffy atmosphere. As light passes through the upper reaches of our atmosphere, it is refracted and distorted, making it much harder to discern objects ...
Second order surface-specific nonlinear optical spectroscopy, e.g. sum-frequency spectroscopy, has made significant and continuous success in revealing the microscopic structures at surfaces/interfaces since the 1990s.
From monitoring concentrations of greenhouse gases to detecting COVID in the breath, laser systems known as frequency combs can identify specific molecules as simple as carbon dioxide and as complex as monoclonal antibodies ...
With the growth in artificial intelligence (AI), 5G systems, cloud computation, and the Internet of Things, transmitters with extremely high capacities are required for data communication. Ultrafast optical modulation is ...
Electro-optic modulators, which convert signals from the electrical to the optical domain, are at the heart of optical communications, terahertz wireless communications, microwave signal processing, and quantum technology. ...
The world woke up on Oct. 3 to learn that Moungi Bawendi of MIT, Louis Brus of Columbia University, and Alexei Ekimov of Nanocrystals Inc. received the Nobel Prize in Chemistry for their discovery and synthesis of semiconductor ...
Owing to its strong electro-optic coefficient and wide transparency window, lithium niobate (LN) has become an attractive photonic material. Thin-film lithium niobate (TFLN) technology has enabled tight mode confinement and ...
Lying between the infrared and millimeter wave regimes, terahertz waves possess many unique properties, prompting numerous compelling imaging applications, such as non-destructive testing, security screening, biomedical diagnosis, ...
From laptop screens to navigation systems, liquid crystals are ubiquitous in modern life. These materials flow like liquids, but their molecules align with one another in a way that resembles the orientational order of a ...
It's getting crowded up there. An increase in military, commercial and scientific launches, coupled with a lower cost for rideshare cubesat launches, means lots more space junk to deal with in coming years. And we're not ...
