## Abstract A novel wideband and highโgain waveguideโamplifier structure, which consists of a folded geometry erbiumโytterbium coโdoped phosphate glass waveguide integrated with a cascaded multilayer medium thinโfilm filter (CMMTFF), is proposed. This CMMTFF consists of some different filterโunit c
