Abstract

As a function of the coupling coefficient in step-index (SI) plastic optical fibers (POFs), the coupling length for achieving the equilibrium mode distribution is determined by a simple algebraic equation and graph, separately for light-emitting diode (LED) and laser launch-beam distributions. One benefit of the proposed function is that it simplifies the determination of the coupling length by eliminating the need to numerically solve the power flow equation (or equivalent) repeatedly for all new values of the coupling coefficient. © 2008 Society of Photo-Optical Instrumentation Engineers.
