8.2-7 Single-Mode Waveguide. What is the largest thickness d of a planar symmetric dielectricwaveguide with refractive indexes n1 = 1.50 and n2 = 1.46 for which there is only one TEmode at A, = 1.3 µm? What is the number of modes if a waveguide with this thickness isused at A, = 0.85 µm instead?%3D

Given that,n1=1.50 & n2=1.46No. of modes, m≈2Vπ, Here only one TE mode is present, So,…
