An InGaAsP light source that has a refractive index of 3.540 is coupled to a step
index fiber that has a core refractive index of 1.480. Assume that the source
size is smaller than the fiber core and that there is a small gap between the
source and fiber.
i) If the gap is filled with a gel that has a refractive index of 1.520, what is
the power loss in decibels from the source into fiber ?
ii) What is the power loss if no gel is used in the small gap ?
