Raman scattering phenomenon can be used to engineer broadband tunable lasers and to generate a broad band of frequencies in the IR spectrum. These light sources are instrumental for probing and detecting ...

Introduction to Thin-film Processes Thin-film deposition is a fundamental step in the fabrication process of micro/nano devices.  A thin film is typically less than 1000 nano-meters in thickness. The ...

Modern Stroke Diagnosis As discussed in a recent article, strokes are one of the most common causes of death in the world. One study found that about 90% of all strokes occur due to cerebral ischemia while ...

For any high-sensitivity laser application, it is essential that all necessary characteristics of the laser beam in use can be quantified and characterized beforehand. To this end, we have written ...

  An Introduction to Nanophotonics: Something Big from Something Small In recent years there has been a lot of work with nanophotonics in optical physics and engineering. This is a part of the rising ...

As we have noted several times previously on our blog, Moore’s law, the phenomenon of exponential growth of computing power due to ever more compact transistor technology, can only continue so far ...

Introduction to Elastography Elastography is a type of imaging modality that provides information on the elastic properties and stiffness of the tissue being reviewed based on spatial distribution. It is ...

Cardiovascular Disease and Photoacoustic Imaging Cardiovascular diseases (CVDs) are the number one cause of death in the world, accounting for 31% of all deaths. This class of diseases includes heart ...

Photoelectronic devices combine the vast use of electronics for processing information with the detection and the manipulation of light. Devices such as photodiodes are useful for detecting incoming light ...

Comparison Between Laser Diode-Pumped Light Sources, LEDs, and HIDs There is a great push in society today to offer light sources that are brighter, clearer, and more energy efficient. For many years now, ...
