ABSTRACT:
An integrated optical component structure designed to operate at a rare earth ion fluorescence wavelength .lambda..sub.1 comprises at least a thin layer of a mixed rare earth fluoride solid solution having the formula (1-x)(M.sub.1-y M'.sub.y F.sub.2)-x TRF.sub.z deposited on a substrate of a monocrystalline semiconductor material where M and M' denote an alkaline earth ion, TRF.sub.z denotes a rare earth fluoride, x is in the range ]0,1[ and y is in the range [0,1]. The component structure finds applications in telecommunications using optical waveguides.
