monomode optical waveguide -> single-mode waveguide (or fiber)

An optical waveguide in which only the lowest order bound mode, which may consist of a pair of orthogonally polarized fields, can propagate at the wavelength of interest.

multimode optical waveguide

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

multimode fiber -> multimode optical waveguide

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

macrobend loss

In an optical waveguide, that loss attributable to macrobending. Macrobending usually causes little or no radiative loss.

marcuse loss theory

A theoretical analysis of radiation loss from planar optical waveguides due to scattering by surface irregularities/surface roughness of the walls of the waveguide.

micro-ring resonator

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...

misalignment loss -> angular misalignment

Angular deviation from the optimum alignment of source to optical waveguide, waveguide to waveguide, or waveguide to detector, resulting in a loss of optical power.

mode

1. The characteristic of how light propagates through a waveguide that can be designated by a radiation pattern in a plane transverse to the direction of travel. 2. The state of an oscillating system...

mode coupling

In an optical waveguide, the exchange of power/energy among modes.

mode distortion -> multimode distortion

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...

mode volume

The number of bound modes that an optical waveguide is capable of supporting.

multimode distortion

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...

multiplexing

The combination of two or more signals for transmission along a single wire, path or carrier. In most optical communication systems this is referred to as wavelength division multiplexing, in which...
