Bending Losses in Optical Fibers
A typical single- or few-mode optical fiber is a thin glass cylinder with an outer diameter of roughly 103 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 10μ containing glass with optical parameters slightly different from that in the cladding . 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.
