Show that, in general, a properly designed waveguide light modulator

requires less electrical driving power than a bulk modulator of the same type

(Bragg, Raman-Nath, etc.) in the same material.

10.2 What change in index of refraction can be induced in a quartz waveguide

3 μm thick and 100 μm wide by an acoustic power of 1 W?
