EE 164 Problem Set 4 Spring 2005 Problem 1: How many TE modes can propagate in the symmetrical slab in Section 4.2 (AlGaAs) if5dλ=? Repeat the problem for10d=and 100. Problem 2: For a certain symmetrical dielectric slab, 11.48n=and21.46n=. The slab is surrounded by air. Draw the ray path of a cladding mode ifθ(the angle in the film) is75D. At what values ofdo the cladding modes no longer appear? Problem 3: Use this equation ()( )11 22nn nLcnτ−∆=to show that the modal pulse
