Researchers have developed a graded grating structure that can be scaled to dimensions compatible with light waves in both the terahertz and telecommunications portion of the spectrum. The achievement ...

The integration of beam splitters and grating structures is central to contemporary developments in optical engineering. These devices, which manipulate light via diffraction and interference, are ...

Lasers find applications across several fields ranging from telecommunications and remote sensing to medicine. There are many ways in which one can generate laser emission, or lasing, from a device or ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Editor's Note: To view a PDF version of the article, Click Here. The commercial introduction of wafer-based, nanofabrication techniques now makes it possible to create a new class of optical ...

People debating politics are well-advised to shed more light than heat. Engineers working in optical technologies have the same aspiration. Light waves transmit data with much greater speed than do ...
