A field of optics describing light propagation in terms of Fourier transforms, often used in the analysis of optical systems and signal processing.

The phenomenon where the phase velocity of a wave depends on its frequency, often causing different colors of light to spread out in an optical medium.

$n_1 \sin(\theta_1) = n_2 \sin(\theta_2)$, where $n_1$ and $n_2$ are the refractive indices and $\theta_1$ and $\theta_2$ are the angles of incidence and refraction, respectively.

A periodic variation in the refractive index of an optical fiber that reflects specific wavelengths of light and transmits others, used for filtering and sensing applications.

An optical device that splits a beam of light into two or more separate beams, commonly used in interferometry.

Devices that manipulate the properties of light such as amplitude, phase, or polarization to encode information onto an optical carrier wave.

Devices used to amplify an optical signal directly, without the need to convert it to an electrical signal first, crucial in long-distance fiber optic communications.

The branch of optics that describes the behavior of light in nonlinear media, where the response is not directly proportional to the electric field of the light.

A process in which a propagating optical wavefront is reversed or conjugated, used to cancel wavefront distortions in optical systems.

A physical process that decomposes an optical signal into its constituent frequencies, analogous to a mathematical Fourier transform.

A device that measures the phase of an optical wavefront, commonly used in adaptive optics to correct for distortions caused by atmospheric conditions.

These are devices that selectively transmit light of different wavelengths, commonly used in lasers, photography, and optical instrumentation.

A type of Bragg grating specifically inscribed in optical fibers, used for filtering, sensing, and laser mode locking among other applications.

An optical component with a regular pattern that disperses light into several beams traveling in different directions, used in wavelength separation and spectral analysis.

A technique for recording and reproducing three-dimensional images of objects, using the interference pattern of light waves.

A property of waves that describes the orientation of their oscillations, with polarized light often used in photography, LCDs, and stress analysis.

Optical devices used to control the spatial amplitude and phase of a light wave, often used in improving image quality by removing aberrations.
