Mode excitation in a multimode optical-fibre waveguide
For normal incidence of a Gaussian beam on a multimode optical fibre, theory predicts that only HE(1m) modes are excited, and this is confirmed experimentally for a liquid-core fibre of normalised frequency v = 125. Discrete-mode propagation is observed, indicating that the amount of mode conversion...
