3 Optical Signal Attenuation and Dispersion
Fig. 3.14 a Typical waveguide dispersions and the common material dispersion for three different
single-mode fiber designs; b resultant total dispersions
setup consists of a 2 m length of fiber that contains a single 14-cm-radius loop or
several 14-cm-radius curvatures that add up to one complete loop. Using a tunable
light source that has a full-width half-maximum linewidth not exceeding 10 nm, light
is launched into the fiber so that both the LP 01 and the LP 11 modes are uniformly
excited.
