Repeat Problem 2.1 for the case λ0 = 1.06μm, all other parameters remaining

unchanged.

Repeat Problems 2.1 and 2.2 for a waveguide of thickness t = 6μm.

In a planar waveguide like that of Fig. 2.8 with n2 = 2.0, n3, = 1.6, and n1 =

1, what is the angle of propagation of the lowest order mode (θ 0) when cutoff

occurs? Is this a maximum or a minimum angle for θ 0?
