Abstract
We report Erbium-doped Ti-indiffused single-mode optical waveguides of good quality in LiNbO3 fabricated by Erimplantation followed by annealing. Besides ground state absorption also xcited-tate-bsorption (ESA) has been investigated indicating that even at 1. 48 pm pump wavelength ESA occurs as a three stage process. The guided-wave spontaneous fluorescence was investigated. In a " pump and probe" experiment for the first time wavelength ranges could be identified where the stimulated emission overcomes the Er-absorption.This publication has 0 references indexed in Scilit:
