Consider a three layer symmetric waveguide. In the following cases, explain if the number of modes increases or decreases as: a) the width of the waveguide increases b) the wavelength of the light propagating in the waveguide increases c) the index difference between the “core” and the “cladding” regions decreases

- b) the
wavelength of the light propagating in the waveguide increases - c) the index difference between the “core” and the “cladding” regions decreases
Does the effective index of the fundamental mode increase or decrease in each of the three cases above?
