Abstract
We show the possibility of a new kind of passive nonlinear-optical dev ice: an optical power filter made of graded-index single-mode fiber (S MF) and a nonlinear medium (NLM). It is shown that, only for a particu lar power, the mode in the SMF matches the mode in the NLM. The transm ission coefficient from the NLM to the SMF is determined, and it is sh own that a laser beam with a particular power can be filtered out. (C) 1996 Optical Society of America
