WebThe free spectral range (FSR) is defined as the wavelength difference between two successive maxima of the dropped power (or minima of the through power). The resonant configuration next to a resonance found for is approximated as. where the right hand side is obtained as a first order Taylor series expansion for the propagation constant around ... WebApr 18, 2024 · The free spectral range is Δλ (shown above the graph). The FSR is related to the full-width half-maximum δλ of any one transmission band by a quantity known as the finesse : F = Δ λ δ λ = π 2 arcsin ( 1 / F), where F = 4 R ( 1 − R) 2 is the coefficient of finesse, and R is the reflectivity of the mirrors. This is commonly ... WebThe free spectral range of the interferometer is defined as the change in wavelength necessary to shift the fringe pattern by one fringe. Nλ =(N - 1)(λ + Δλ FSR ), Δλ FSR = λ/(N - 1) ~ λ/N, since N is very large. periods suddenly become irregular
