This calculator computes the mode-field diameter of the fundamental mode in a step-index fiber using Marcuse's equation. |
Here, we calculate the fundamental mode field diameter in step-index fiber. Enter your values, then click calculate. |
MFD is determined by the numerical aperture (NA) and cut-off wavelength of the fiber and is related to the diameter of the fiber core. |
Mode Field Diameter Calculator · MFD= 2a(0.65+1.619V3/2+2.879V6) · V= 2πλaNA. |
The Mode Field Diameter ( M F D ) is calculated by considering the core radius, numerical aperture, and the wavelength of the light used. |
To determine the mode fiber diameter (MFD) of the fundamental mode in a given single-mode fiber (SMF) by a measurement of its far-field. Apparatus. Bread board, ... |
For calculating the effective mode area from the mode field diameter, one can thus apply a correction factor, which depends on the wavelength [6]. |
The MFD represents a measure of the transverse extent of the electromagnetic field intensity of the mode in a fiber cross-section. Best coupling occurs between ... |
