Question

Q1: A one dimensional potential barrier is shown in the figure below. Calculate the transmission
coefficient.
E
E >V1 > V2
V1
V2
x=0
x= a
With wavefuction in each region as follow:
41(x) = eikix + Be¬ik1x,
%3D
42(x) = Cek2* + De-ik2*,
And
3(x) = Eeik3x
%3D
Then use: h = 6.625 10-34Js, m = 9.109 10-31Kg, e = 1.602 10-19, E = 5 e, V1 = 0.6 E, V2 =
%3D
2mE
E, k2 =
2m(E-V1)
,k3
2m(E-V2)
0.4 E, k, :
to find the value transmission coefficient.

Modal Dispersion. Light of wavelength = 0.633 µm is transmitted through a mirror waveguide of mirror separation d = 10 μm and n = 1. Determine the number of TE and TM modes. Determine the group velocities of the fastest and the slowest mode. If a narrow pulse of light is carried by all modes for a distance 1 m in the waveguide, how much does the pulse spread as a result of the differences of the group velocities?
