nf = = P7a. A planar dielectric waveguide is formed by a 1.5 um thick film, with refractive index 1.8, bounded by a cover with refractive index nc 1.7, and a substrate with ng < nc. Knowing that the cutoff wavelength for the TE, mode is 1TE0...0. = 5.9684 um: (a) Determine the refractive index of the substrate. (b) Calculate the number of TE modes that can be launched in the waveguide with a light with wavelength to = 500 nm.
