Pump-probe experiments at 1.54 μm on silicon-rich silicon oxide waveguides
Optical pump-probe measurements were performed on slab waveguides containing excess silicon in the form of nanoclusters or nanocrystals and erbium. The measurements were performed by prism coupling a 1.54μm probe beam into a waveguide formed by silicon-rich oxide and monitoring its intensity and temporal response as the waveguide was optically pumped from above with a chopped 477nm excitation source. Induced absorption (losses) of the 1.54μm probe beam in erbium-doped and undoped silicon-rich...[Show more]
