Brillouin Shift Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brillouin shift = (2*Mode Index*Acoustic Velocity)/Pump Wavelength
ν_b = (2*n̄*v_a)/λ_p
This formula uses 4 Variables

Variables Used

Brillouin shift - (Measured in Hertz) - Brillouin shift is measurement of frequency shift of light due to its interaction with acoustic phonons or mechanical vibrations in a material.
Mode Index - Mode Index quantifies how light propagates in a waveguide or fiber, particularly within specific optical modes.
Acoustic Velocity - (Measured in Meter per Second) - Acoustic Velocity represents the speed at which acoustic waves travel in a medium.
Pump Wavelength - (Measured in Meter) - Pump Wavelength refers to the distance between two consecutive peaks or troughs of an electromagnetic wave in the optical spectrum.

STEP 1: Convert Input(s) to Base Unit

Mode Index: 0.02 --> No Conversion Required
Acoustic Velocity: 0.25 Meter per Second --> 0.25 Meter per Second No Conversion Required

Diameter of Fiber

Go Diameter of Fiber = (Wavelength of Light*Number of Modes)/(pi*Numerical Aperture)

Power Loss in Fiber

Go Power Loss Fiber = Input Power*exp(Attenuation Coefficient*Length of Fiber)

Fiber Attenuation Coefficient

Go Attenuation Coefficient = Attenuation Loss/4.343

Number of Modes using Normalized Frequency

Go Number of Modes = Normalized Frequency^2/2
