Paper Abstract

Short amplifying waveguides in which the dopand is confined to the waveguide core were realized by a new glass processing technology with high demands to the optical and thermal properties of the core, cladding and substrate glass. By the improvement of the etching procedures primary structures with a roughness of less than 50 nm were obtained. Simulations, which showed that in a 12 cm waveguide 20 dB gain can be achieved at 1549 nm, were made to evaluate the potential of the amplifier. Gain measurements were performed in waveguides with a dopand concentration of 3 wt.% erbium and an internal gain of more 3.7 dB was achieved in a 1.8 mm glass waveguide at a wavelength of 1549 nm.
