Nanocluster sensitized erbium-doped silicon monoxide waveguides

Optical gain at 1.54 μm in erbium-doped silicon nanocluster sensitized waveguide

Absorption bleaching by stimulated emission in erbium-doped silicon-rich silicon nitride waveguides.

Stimulated emission from sensitized erbium ions in silicon-rich silicon nitride is demonstrated by pump-probe measurements carried out in waveguides. A decrease in the photoinduced absorption of the probe at the wavelength of erbium emission is observed and is attributed to stimulated emission from erbium excited indirectly via localized states in the silicon nitride matrix.

Erbium doped silicon nanoclusters for Microphotonics

To my parents Cover: contour plot showing the simulated number of excited Er ions per Si nan-ocluster, as a function of Er concentration and pump power. Brighter gray tones represent higher values. More details can be found in Fig. 4.26 within this thesis, on page 102. The work described in this thesis was mainly performed at the Laboratory for MAterials and Technologies for the Information and...

Monolithic integration of erbium-doped amplifiers with silicon-on-insulator waveguides.

Monolithic integration of Al2O3:Er3+ amplifier technology with passive silicon-on-insulator waveguides is demonstrated. A signal enhancement of >7 dB at 1533 nm wavelength is obtained. The straightforward wafer-scale fabrication process, which includes reactive co-sputtering and subsequent reactive ion etching, allows for parallel integration of multiple amplifier and laser sections with silico...

Characterization of erbium doped lithium niobate crystals and waveguides

Optical planar waveguides have been fabricated by the titanium in-diffusion process in lithium niobate crystals activated with erbium ions. The waveguides were studied by m-line technique in order to recover the index profile. The effect of the Ti in-diffusion on the structural and spectroscopic properties of the lithium niobate crystals was investigated by Raman and photoluminescence spectrosc...
