| Abstract: |
We have systematically measured the differential stress-optic coefficient, ΔC, in a number of poly(methyl methacrylate) (PMMA) fibers drawn with different stress, ranging from 2 up to 27 MPa. ΔC was determined in transverse illumination by measuring the dependence of birefringence on additional axial stress applied to the fiber. Our results show that ΔC in PMMA fibers has a negative sign and ranges from −4:5 to −1:5 × 10−12 Pa−1, depending on the
drawing stress. Increase of the drawing stress results in greater initial fiber birefringence and lower ΔC.
