Consider a tunable 2×2 MZI that is constructed on an electro-optical crystal having an effective index of 1.5.
(a) If the MZI is used to combine two wavelength channels separated by 0.2 nm, find the required L if the wavelength is centered at 1550 nm.
(b) Assume the parameter L is varied by electrically modulating the refractive index of the electro-optical crystal. What is the index change needed if the waveguide length is 100 mm Note that
the effective optical path length L effin a waveguide is given by L eff= n eff.
