# Bending Losses in Optical Fibers

Chapter

## Abstract

A typical single- or few-mode optical fiber is a thin glass cylinder with an outer diameter of roughly 10^{3} *μ*. Most of the fiber makes up what is called the cladding, but at its center is an an inner core with a diameter of roughly 10*μ* containing glass with optical parameters slightly different from that in the cladding [1]. This is shown schematically in Figure 1. The inner core traps light because its index of refraction is larger than that in the surrounding cladding.
