Fiber bragg grating-circulator systems having reduced ASE

摘要: A light source system for fiberoptic networks is presented. The has a laser source, an optical circulator, fiber section having at least one Bragg grating, and output port. circulator receives through its first port passes the to circulator's second received passed third connected source. grating reflectivity centered about predetermined wavelength. port, which unconnected of system. Light from wavelength with significantly reduced ASE.
