Abstract :
A method which allows numerical calculations of aberration-induced coupling loss with arbitrary coupling optics for single-mode fibers is discussed. It makes use of standard ray-tracing procedures and is applicable to coherent sources, like laser diodes (LDs), and partially coherent sources, such as light-emitting diodes (LEDs). Good agreement between calculated and measured coupling loss is found for LDs and edge-emitting LEDs. Some consequences of lens aberrations for coupling-lens design are discussed
