In this paper, we numerically investigate the formation and propagation characteristics of waveguides written by luminescence-induced spatial solitons (LISSs). Such waveguides, realized in erbium-doped lithium niobate crystals by photorefractive and Pockels effects, are analyzed in the transient regime by using a spatiotemporal numerical code for the photorefractive nonlinearity as well as for the erbium emission and light propagation within the induced waveguide. These calculations highlight a great LISS feasibility. Optical characterization of the waveguides indicates light propagation losses lower than 0.05 dB/cm at 1550 nm, pointing out high potentialities of LISS waveguides for active and passive electrooptic devices.

Abstract
In this paper, we numerically investigate the formation and propagation characteristics of waveguides written by luminescence-induced spatial solitons (LISSs). Such waveguides, realized in erbium-doped lithium niobate crystals by photorefractive and Pockels effects, are analyzed in the transient regime by using a spatiotemporal numerical code for the photorefractive nonlinearity as well as for the erbium emission and light propagation within the induced waveguide. These calculations highlight a great LISS feasibility. Optical characterization of the waveguides indicates light propagation losses lower than 0.05 dB/cm at 1550 nm, pointing out high potentialities of LISS waveguides for active and passive electrooptic devices.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
