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.

1.The core of an optical fiber is made out of a transparent material with a refractive index of 1.50 and the cladding is made out material with a refractive index of 1.44. As shown in the figure, a monochromatic light ray travels in air incident on the one side of the optical fiber and refracted. After that, the refracted ray will enter the core-cladding interface with its corresponding critical angle C. a) Calculate the value of 0? b) Find the...

Question 19 of 31 > The index of refraction for a certain type of glass is 1.637 for blue light and 1.607 for red light. A beam of white light (one that contains all colors) enters a plate of glass from the air, r1, at an incidence angle of 37.05. What is the absolute value of 8, the angle in the glass between blue and red parts of the refracted beams? 18] Question 18 of 31 > The core...

3.) An optical fiber is covered by a layer of glass, to protect its surface. The index of refraction of the core is n1 = 1.8, and that of the protective layer is n2 = 1.5. The diameter of the core is d= 0.2mm. a. Calculate the critical incident angle at the interface between the core and the protective layer, at which total reflection occurs!

(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...
