Optical physics is the study of the generation of electromagnetic radiation, its properties, and its interaction with matter, particularly its manipulation and control. It is…

A nanodevice created by Finnish researchers can detect microwave radiation’s absolute power down to the femtowatt level at extremely low temperatures, a scale a trillion…

A phosphoroscope is a piece of experimental equipment invented by physicist A. E. Becquerel in 1857 to measure how long it takes a phosphorescent material…

Phosphorescence, like fluorescence, is a type of photoluminescence. When exposed to shorter wavelength light (radiation), a phosphorescent substance will glow, absorbing the light and reemitting…

According to the IUPAC definition, Luminescence is the “spontaneous emission of radiation from an electronically excited species (or from a vibrationally excited species) that is…

Photoluminescence is a phenomenon in which a material emits light after absorbing photons. It is a type of luminescence, which refers to the emission of…

Photonic molecules are a theoretical natural form of matter that can also be created artificially in which photons bind to form “molecules.” They were predicted…

Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a phenomenon that occurs when a…

A fundamental model in quantum mechanics that describes the behavior of a particle in a harmonic potential well is the quantum harmonic oscillator. It is…

A structure formed by reflecting faces on two sides of a spacer layer or optical medium, or by wrapping a waveguide in a circular fashion…

A pulsed field magnet is a strong electromagnet that is powered by a brief pulse of electric current through its windings rather than a continuous…

A magnetoquasistatic field is a type of electromagnetic field characterized by a slowly oscillating magnetic field. Low-frequency induction from a magnetic dipole or a current…
