4 Modal Dispersion. Light of wavelength A, = 0.633 um is transmitted through a mirror waveguide of mirror separation d 10 um and n = 1. Determine the number of TE and TM modes. Determine the group velocities of the fastest and the slowest mode. If a narrow pulse of light is carried by all modes for a distance 1 m in the waveguide, how much does the pulse spread as a result of the differences of the group velocities?
