Repeat Problem 10.8 for a modulation frequency = 100 MHz.

A Bragg-type modulator made in fused quartz is used to modulate light of

wavelength = 6328 A. The transmitted intensity in the absence of the acous- ˚

tic beam is 200 mW/cm2 and the 0th order intensity in the presence of the

beam is 175 mW. The length of the modulator in the direction parallel to the

optical beam is1 cm and the thickness of the modulator is 1 mm. If the power

of the acoustic beam is 500 mW, what is the maximum modulation depth?
