OPTICAL WAVEGUIDE AMPLIFIERS IN HIGHLY ER-DOPED SILICA GLASS SUBSTRATES. Autori: . |

Rezumat:
Short amplifiers are currently attracting increased interest, especially for use in integrated optics. In this study the simulated gain performance and noise figure of Erbium doped on Silica glass substrate pumped in the forward direction are obtained taking into account the up conversion effect from the Er3+ levels (4I13/2 and 4I11/2). The influence of waveguide length, pump power, Er-doping concentration and the co-operative up-conversion coefficient on the gain curves and on the waveguide noise figure is studied. Optimum results are obtained using a 3-cm length waveguide at Erbium ions density of NEr (15×1026 at/m3) and at the up-conversion coefficient value of 1x10−24 m3/s−1. The up-conversion process, however, puts limits on both the amplifier gain and the maximum favorable concentration. Keywords: Erbium, waveguide amplifiers, optical amplifiers, waveguide components
