How to Calculate Cutoff Wavelength?
Cutoff Wavelength calculator uses Cutoff Wavelength = (2*Refractive Index*Plate Distance)/Mode Number to calculate the Cutoff Wavelength, The Cutoff Wavelength formula is used to calculate the cutoff wavelength of a waveguide, such as an optical fiber, for a given mode number m. The cutoff wavelength is the wavelength at which a particular mode ceases to be guided by the waveguide. Cutoff Wavelength is denoted by λ_{cm} symbol.
How to calculate Cutoff Wavelength using this online calculator? To use this online calculator for Cutoff Wavelength, enter Refractive Index (n_{r}), Plate Distance (p_{d}) & Mode Number (m) and hit the calculate button. Here is how the Cutoff Wavelength calculation can be explained with given input values -> 2124 = (2*2*0.2123)/4.
