Abstract
A device for distributing light energy comprises a chamfered inlet fiber (2) which is coupled to a plurality of outlet fibers (3) which are grouped together in a matrix. The coupling is performed by a diffraction grating (5) which is inclined relative to the chamfered inlet fiber at such an angle that the diffracted beam is a parallel beam, and the matrix of outlet fibers is disposed on the path of said outlet beam. Such a device is applicable to optical fiber distribution systems.
