Consider two coupled dielectric slab waveguides .The two waveguides are identical to one another and have coupling coefficient: C=C12=C21=500 m-1 a)Find the length of the coupled waveguide structure that allows for complete power transfer from waveguide 1 to waveguide 2. b)Now assume that light is launched into both waveguides at the same power P0 and the same phase,but with linear X polarization in waveguide 1 and linear Y polarization in waveguide 2.Write expressions for the power and the polarization (normalized Jones vector)of the light in each waveguide as a function of the distance traveled.Assume that propagation constants and coupling coefficients are the same for both X and Y polarizations.
