EXERCISE 21.2-1 Intensity Modulation Using the Kerr Effect. Use (21.2-23) and (21.2-24) to determine an expression for the phase shift $?$ and the phase retardation $?$ in a longitudinal Kerr modulator made of an isotropic material, as functions of the applied voltage $V$. Derive expressions for the half-wave voltages $V_{?}$ in each case. $\begin{array}{l}{n}_o(E)?n?\frac{1}{2}{n}^3{\mathrm{s}}_{12}{E}^2\\ n_e(E)?n?\frac{1}{2}{n}^3{\mathrm{s}}_{11}{E}^2\end{array}$
