| Abstract(in English) | We propose high gain optical waveguide amplifiers using rare-earth-doped garnet crystalline thin films in place of fiber amplifiers. Recently we find that it is effective to select Er^<3+> as active ion in order to operate near l.55mm wavelength of the optical fiber transmission window, and fabricate slab waveguides of 1.3 at.% Er^<3+>-doped yttrium alminium garnet (Er:YGG) on the YAG substrates by RF sputtering. In this report, attenuation spectra of the waveguide showing the peaks that are due to absorption of the erbiumions are measured, and then best pumping wavelengths near 0.98μm and 1.48μm are determined. In order to make three-dimensional waveguide amplifier, we suppose strip-loaded waveguide consisting of Er:YGG thin film on YAG substrate with ZnO as loading strip, and analyze the number of modes by effective index method. |
