26 December 1984 Determining Single-Mode Fiber Index Profiles From Near-Field Radiation Patterns
Author Affiliations +
Single-mode fiber refractive index profiles are determined from the intensity patterns acquired by the Transmitted Near-Field (TNF) method. The formula used for this calculation is derived from the transverse electric field form of the scalar wave equation. In addition, the singularity which occurs as we approach the center of the fiber has been remedied. Theoretical and experimental results are presented for one dimensional TNF intensity distributions.
