Abstract :
Simple expressions are derived to estimate the coupling efficiency and sensitivity of an LED butt-coupled to a single-mode fibre. The concept of the single-mode numerical aperture is revised so as to incorporate the wave nature of the coupling process. Our analysis agrees well with experimental results.
