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…

Silicon photonics is the study and application of photonic systems that use silicon as an optical medium. Silicon is typically patterned with sub-micrometre precision into…

The conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry, is known as…

A Halbach array is a special arrangement of permanent magnets that augments the magnetic field on one side of the array while canceling the field…

An electromagnet is a type of magnet that generates a magnetic field by using an electric current. Electromagnets are typically made of wire wound into…
