Abstract

Due to the absence of interference effects and instabilities, LEDs may be preferable to lasers for many communication applications. Normally LEDs are used with multimode fibers,¹ since their coupling efficiency to monomode fibers is considered too small. In this paper we show, however, that with edge-emitting diodes sufficient light power can be launched even into a monomode fiber to span more than 10 km.
