Unformatted text preview: f = 1.5, n s = 1.47, l = 1.0 m, determine the fraction of power carried in the cladding if the guiding layer is 3 m thick. Hint: Calculate the integral of the Poynting vector to get power 4. Consider a fiber with core index 1.5, cladding index 1.495, and a core radius 5 m. a. How many modes exist for a wavelength of 1 m b. How many modes exist for a wavelength of 0.5 m? List each mode and its cutoff condition Hint: Read section 7 on page 89 of the book...
