Researchers from the Harbin Institute of Technology at Shenzhen and Shanxi University have created a new configuration for waveguide connected microdisks (WCM). Their method could significantly reduce ...

A team of researchers from the Erasmus University Medical Center in Rotterdam, Netherlands optimized the use of intravascular imaging in the detection of coronary artery diseases via catheters. They ...

Gyroscopes are devices that measure rotational changes. On first mention, most people picture the beautifully rotating classical mechanical gyroscope. Although widely used till the late 1900s, optical ...

Having discussed the history and physics of AR coats, our final article discusses the standard AR coating techniques via application of thin films. The basic principles of AR coating application remain the ...

Photonics Technologies in Farming Farmers everywhere face the same daunting task: the world population is growing at an exponential rate, and food supply has to keep up. There is practical limits to a ...

Introduction to Adaptive Optics Anyone who has ever driven down the road on a hot day has probably noticed steam radiating off the pavement. However, if you looked closely enough, the steam was actually ...

Introduction to Diffraction Gratings Diffraction gratings are optical components that diffract and separate light into several beams at different angles by wavelength. Their working principle is hinged ...

Introduction to Optical Parametric Oscillators In 1961, Peter Franken and his group at the University of Michigan were the first to use  nonlinear materials to produce optical harmonics. This method ...

Introduction A single human hair is approximately 80,000-100,000 nanometers wide. Now, imagine a distance that measures several hundred times smaller than a human hair. Such small distances are often ...

Ultrafast amplifiers are devices that can boost the pulse energy and the average powers of ultrashort pulse trains. While the prospect of applying ultrafast amplifiers on laser systems is appealing, it ...
