A method and means for coupling information or signal power into or out of fiber optics for integrated optical waveguides. The coupling consists of selectively doping with impurity ions such as rare earth or transition metal ions which are excited to fluorescene within the waveguide by the frequency of the transmitted carrier wave. The fluorescent emission is then detected at right angles to the fiber using conventional photodetectors and amplifiers. Author
