Figure 13.24 Intensity plots for the
LP 01 mode in a weakly guiding step
index fiber. Traces are shown for V = 1.0
(solid), V = 1.2 (dashed), and V = 1.5
(dotted), corresponding to increases in
frequency in those proportions. Dashed
vertical lines indicate the core/cladding
boundary, at which for all three cases,
the J 0 radial dependence in the core
connects to the K 0 radial dependence in
the cladding, as demonstrated in Eq.
(160). The migration of mode power
toward the fiber axis as frequency
increases is evident.
