Optical Fiber Vibration and Acceleration Model



Neil Ashby, David A. Howe, Jennifer A. Taylor, Archita Hati, Craig W. Nelson


We derive expressions for the group velocities of transverse electric and transverse magnetic electromagnetic waves in a stretched single-mode fiber. Stretching can occur either as a result of temperature changes of the spool on which the fiber is wound, or as a result of axial vibrations causing acceleration and hence deformation of the spool. Long single-mode fibers are typically used in optical frequency combs, where the group velocity plays a central role in determining the oscillator frequencies. The present idealized calculation assumes there is a fractional length change, (δ-l)/l that results in stress in the fiber, that changes the optical properties of the fiber, and hence the group velocities, through its stress-optic coefficients. The principal result of the present calculation is that for optical frequency combs, the main effect on the optical comb frequencies comes from the change of length itself rather than from the change in group velocities.
