چکیده
Deposition and micro-structuring of Al2O3:Er layers with low background losses (0.11 dB/cm) and lifetimes up to 7 ms have been optimized for active devices. Net gain of 0.7 dB/cm at 1533 nm has been measured. ©2008 Optical Society of America OCIS codes: (140.4480) Optical amplifiers; (140.5680) Rare earth and transition metal solid-state lasers

Optimized Deposition and Structuring of Reactively Co-Sputtered Al2O3:Er Waveguide Layers with Net Optical Gain
Growth of reactively co-sputtered Al2O3 layers and micro-structuring using reactive ion etching have been optimized, resulting in channel waveguides in the as-deposited layers with optical propagation losses as low as 0.21 dB/cm. For active functionality, Erdoped Al2O3 layers have also been deposited by co-sputtering from a metallic Er target. At relevant dopant levels (~10 cm) lifetimes of the...
متن کاملCooperative upconversion as the gain-limiting factor in Er doped miniature Al2O3 optical waveguide amplifiers
Erbium doped Al2O3 waveguide amplifiers were fabricated using two different doping methods, namely Er ion implantation into sputter deposited Al2O3 , and co-sputtering from an Er2O3 /Al2O3 target. Although the Er concentration in both materials is almost identical ~0.28 and 0.31 at. %!, the amplifiers show a completely different behavior. Upon pumping with 1.48 mm, the co-sputtered waveguide sh...

This contribution reviews our recent results on rare-earth-ion-doped integrated amplifiers and lasers. We have concentrated our efforts on complex-doped polymers [1], amorphous Al2O3 [2], and crystalline potassium double tungstates [3]. A polymer host material, based on a cycloaliphatic diepoxy cured with a fluorinated dianhydride, has been developed [4]. When activated with the rare-earth-ion-...

Focused ion beam (FIB) etching is receiving increasing attention for the fabrication of active integrated optical components such as waveguide amplifiers and lasers. Si-technology compatible low-loss Al2O3 channel waveguides grown on thermally oxidized silicon substrates have been reported recently. We used FIB milling for reflection grating definition on Al2O3 channel and ridge waveguides. Str...

Reactive co-sputtering has been applied as a low-cost method for deposition of Al2O3:Er layers. Channel waveguide fabrication has been optimized and results in waveguides with low background losses (0.21 dB/cm), demonstrating the feasibility of realizing active photonic devices. A net optical gain of 0.84 dB/cm for a 1533-nm signal has been obtained in a 700-nm-thick Er-doped Al2O3 waveguide pu...
