Driven by applications in chemical sensing, biological imaging and material
characterisation, Raman spectroscopies are attracting growing interest from a variety of …

Until very recently, handheld spectrometers were the domain of major analytical and security
instrument companies, with turnkey analyzers using spectroscopic techniques from X-ray …

The emergence of silicon photonics over the past two decades has established silicon as a
preferred substrate platform for photonic integration. While most silicon-based photonic …

A frequency mixer is a nonlinear device that combines electromagnetic waves to create
waves at new frequencies. Mixers are ubiquitous components in modern radio-frequency …

Chemical vapour deposition (CVD) is a powerful technology for producing high-quality solid
thin films and coatings. Although widely used in modern industries, it is continuously being …

Light at wavelengths in the near-infrared (NIR) region allows for deep penetration and
minimal absorption through high scattering tissue media. NIR light has been conventionally …

Nonlinear fiber optics concerns with the nonlinear optical phenomena occurring inside
optical fibers. Although the field ofnonlinear optics traces its beginning to 1961, when a ruby …

A topical review of numerical and experimental studies of supercontinuum generation in
photonic crystal fiber is presented over the full range of experimentally reported parameters …

Photonic crystal fibers guide light by corralling it within a periodic array of microscopic air
holes that run along the entire fiber length. Largely through their ability to overcome the …

This paper introduces and discusses the main aspects of ultrashort laser pulse filamentation
in various transparent media such as air (gases), transparent solids and liquids. The …
