An Optical Fiber Mode Analyzer Using the Refraction from the Oblique Section
Summary :
In this paper, the authors propose a new mode analyzer. This mode analyzer is composed of an obliquely polished optical fiber and a high index prism placed in contact with the oblique section. Modes which have the different equivalent refractive indices are separated due to the different angles of refraction. A mode analyzer using a focusing fiber was made, and modes were successfully separated. The refractive index n(0) at the center axis, the coefficient g of the parabolic term in the refractive index distribution, and the refractive index in the cladding were evaluated from the measurement of angles of refraction. The obtained value of refractive index n(0) at the center axis almost agreed with the value obtained by the interference method. As the application of this mode analyzer, the measurement of group-delay differences of modes and amplitude distribution of modes in a long fiber, and the measurement of the constants of fiber are considered.
