Patent ID: 8406599

Claim:
A method for creating a composite material for fabricating an optical fiber, comprising: selecting multiple constituents and a concentration for each constituent; obtaining values for various physical parameters for each constituent; conceptually dividing a unit length model rod into a number of segments, wherein the number equals the number of constituents and wherein each segment is associated with a separate one of the constituents; computing origin locations for the segments; computing a longitudinal acoustic velocity for an assumed composite material created at an appropriate temperature using above values; computing a photoelastic constant for the assumed composite material using above values; computing an acoustic frequency for the assumed composite material using above values; computing an acoustic attenuation coefficient for the assumed composite material using above values; computing a Brillouin Spectral Width for the assumed composite material using above values; computing a Brillouin Gain Coefficient for the assumed composite material using above values; and if the computed Brillouin Gain Coefficient is greater than a preselected value, repeating the above, otherwise, mixing the constituents at an appropriate temperature.
