Photonics Dictionary: M

A shaft, spindle or any object generally passed through a workpiece to hold, support or shape a particular piece during its machining process or its practical use. In fiber optics, optical fibers are...

A micro-ring resonator is a compact optical device that utilizes the resonant behavior of light within a small ring-shaped waveguide structure to selectively enhance or filter certain wavelengths of...

Synonym for multimode distortion. Also called mode dispersion.

In optics, "mode beating" refers to an interference phenomenon that can occur in laser systems with multiple longitudinal modes. Longitudinal modes are specific electromagnetic field patterns that...

Synonym (regarded by some as erroneous) for multimode distortion, which see.

A device used in measuring the attenuation of multimode optical fibers. A short reference length of fiber when combined with the mode filter has approximately the same angular output distribution of...

A multimode laser characteristic defined as the ratio of power loss for the second mode to that of the lowest mode.

In optics, a motion controller refers to a device or system that precisely controls the movement of optical components, such as mirrors, lenses, stages, or other elements within an optical setup. The...

Used in computer design for optical systems with common parts and different applications.

In an optical waveguide,- typically a multimode fiber - the distortion resulting from differential mode delay, i.e. axial rays (modes), with the shortest path length, will have the shortest...

A laser that produces emission in two or more transverse or longitudinal modes.

An optical waveguide that will allow more than one bound mode to propagate.
