Field Distribution. The transverse distribution um (y) of the electric-field complex amplitude of a TE mode in a slab waveguide is given by (8.2-10) and (8.2-13). Derive an expression for the ratio of the proportionality constants. Plot the distribution of the m 0 TE mode for a slab waveguide with parameters n1 = 1.48, n2 = 1.46, d 0.5 um, and X, = 0.85 um, and determine its confinement factor (percentage of power in the slab).
