Abstract :
A novel method for evaluating the effective cutoff characteristic in an optical fiber is described both numerically and experimentally. It is clarified that the proposed technique, which is based on far-field pattern measurement under different launching conditions, can be applied not only to conventional single-mode fiber but also to a fiber with improved bending loss.
