The coupling efficiency is defined as a measure of amount of power emitted from an optical source that can be coupled into a fiber.

$\therefore$ Coupling efficiency

$ɳ_c = \frac{P_{fiber}}{P_{source}}$

where

$P_{fiber}$ is the power coupled into the fiber

$P_{source}$ is the power emitted from source

The coupling efficiency also …
