NAME

Materials for optics

DESCRIPTION

Materials for optics are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each task is strongly wavelength dependent, thus a full understanding of the interaction between light and matter is vital.

8 skos:definition Materials for optics are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each task is strongly wavelength dependent, thus a full understanding of the interaction between light and matter is vital.

38 skos:definition Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors. Lasers add a mechanism for optical feedback, such as mirrors, that stimulates further emission and generates a high-intensity beam of radiation.

57 skos:definition Materials science is an interdisciplinary field concerned with the understanding and application of the properties of matter. Materials scientists study the connections between the underlying structure of a material, its properties, its processing methods and its performance in applications.

77 skos:definition Metamaterials are engineered structures designed to interact with electromagnetic radiation in a desired fashion. They usually comprise an array of structures smaller than the wavelength of interest. These so-called meta-atoms can interact with the electric and magnetic components of light in a way that natural atoms do not.

88 skos:definition Nanophotonics and plasmonics is the study of light at the nanometre-scale. Light can only be focused to a spot roughly half its wavelength in size (a few hundred nanometres for visible light). This limit can be surpassed by coupling light to electrons at the surface of a metal and creating surface plasmons.

96 sg:ontologies/subjects/optical-physics
97 skos:definition Nonlinear optics is the study of how intense light interacts with matter. The optical response of a material usually scales linearly with the amplitude of the electric field. At high powers, however, the material properties can change more rapidly. This leads to nonlinear effects including self-focusing, solitons and high-harmonic generation.

105 sg:ontologies/subjects/optical-materials-and-structures
106 skos:definition Photonic crystals are periodic optical structures that can control the flow of light. Multiple reflections from surfaces separated by a distance similar to the wavelength prevent an optical beam from propagating through the crystal. Photonic crystal devices can therefore force light around sharp bands or even trap it entirely.

115 skos:definition Quantum optics is the study of how individual quanta of light, known as photons, interact with atoms and molecules. This includes studying the particle-like properties of photons. Photons have been used to test many of the counter-intuitive predictions of quantum mechanics, such as entanglement and teleportation, and are a useful resource for quantum information processing.

124 skos:definition Ultrafast photonics is the study of light and its interaction with matter on short timescales, typically less than a picosecond. This includes investigating processes that occur in atoms and molecules, such as the dynamics and correlations between electrons during ionization, and often employs ultrafast lasers or mode-locked lasers.
