1. (a) A laser beam enters an optical fiber with an incident angle of 6max as shown in Figure 1. Its corresponding refracted light is subsequently incident on the boundary between the core and the cladding whose refractive indices are ni and n2, respectively. The second incident angle satisfies the critical angle, 0c, for total internal reflection. Derive the Numerical Aperture (NA) of the fiber that dictates the maximum acceptance angle, amax.

The figure depicts a simplistic
optical fiber: a plastic core (n1 = 1.54) is surrounded by a
plastic sheath (n2 = 1.46). A light ray is incident on one end of
the fiber at angle ?. The rays is to undergo total internal
reflection at point A, where it encounters the core-sheath
boundary. (Thus there is no loss of light through that boundary.)
What is the maximum value of ? that allows total internal
reflection at A?

(2 points) Optical fibers are made of glass, where light is trapped inside the fiber by total internal reflection. This example is not a fiber geometry and doesn't include the gradations in refractive index that are used, but still illustrates the point of total internal reflection. Suppose you have a piece of glass, with light incident from the glass side toward an air interface. The refractive index of the glass is 1.45. What is the critical angle where all light...

Dispersion in a window pane. In Figure (a) below, a beam of white light is incident at angle 6, -50° on a common window pane (shown in cross section. For the pane's type of glass, the index of refraction for visible light ranges from 1.527 at the blue end of the spectrum to 1.518 at the red end. The two sides of the pane are parallel. What is the angular spread of the colors in the...
