Abstract
A device for coupling out of or into a transmission system which carries light signals is provided. A first optical fiber having a Bragg grating therein has its cladding optically coupled to a second optical fiber having a Bragg grating therein so as to allow at least a predetermined wavelength of light incident upon the first Bragg grating to be forward coupled from the core to the cladding and then to the core region of the second optical waveguide via the second Bragg grating.
