The present invention relates to a potentially inexpensive light source for multichannel wavelength- division-multiplexed (WDM) applications. The high-power amplified spontaneous emission (ASE) from a fiber amplifier, which is already in the optical fiber, is efficiently divided into many channels using a WDM demultiplexer. This "spectrum-sliced" ASE is used as light sources for WDM systems rather than several wavelength-selected DFB lasers.
Source lumière potentiellement économique pour applications MRL (multiplexage par répartition en longueur d'onde) multicanaux. L'émission spontanée amplifiée (ASE) à grande puissance provenant d'un amplificateur à fibre, qui est déjà dans la fibre optique, est divisée efficacement en de multiples canaux au moyen d'un démultiplexeur MRL. L'ASE ainsi « découpée » est utilisée comme sources lumineuses pour des systèmes MRL au lieu de plusieurs lasers DFB (à rétroaction répartie) à longueur d'onde sélectionnée.
