Exercise 11
On the same graph, plot the maximum cou­pling efficiencies as a function of the source radius r s for the following fibers:
( a ) Core radius of 25 m and NA = 0.16.
( b ) Core radius of 50 m and NA = 0.20.
Let r s range from 0 to 50 m. In what regions can a lens improve the coupling efficiency
