Rare-earth-ion-doped Al2O3 for integrated optical amplification
Erbium-doped aluminum oxide channel waveguides were fabricated on silicon substrates and their characteristics were investigated for Er concentrations ranging from 0.27 to 4.2 × 10 cm. Background losses below 0.3 dB/cm at 1320 nm were measured. For optimum Er concentrations in the range of 1 to 2 × 10 cm, internal net gain was obtained over a wavelength range of 80 nm (1500-1580 nm) and a peak ...
متن کاملFocused Ion Beam Milled On-chip Resonator Nanostructures for Applications in Rare-Earth-Ion-Doped Al2O3 Active Waveguides
Reflection gratings on Al2O3 channel waveguides were defined by focused ion beam milling. Fabry-Perot microcavities were fabricated and improved performance upon annealing was demonstrated, making them viable candidates as resonators for on-chip waveguide lasers.
متن کاملSynthesis and Characterization of High Coercivity Rare-earth Ion Doped
Influence of replacing Sr ions by rare-earth ions (RE) ions on the structural and magnetic properties of high coercivity (Hc) SrFe10Al2O19 hexaferrite have been investigated using X-ray diffraction, transmission electron microscopy, differential scanning calorimeter, and SQUID. A 73% increase in intrinsic coercivity is observed for Al doped SrFe10Al2O19 as compared to that of pure SrFe12O19. Th...
متن کاملRare Earth Ion-Doped Upconversion Nanocrystals: Synthesis and Surface Modification
The unique luminescent properties exhibited by rare earth ion-doped upconversion nanocrystals (UCNPs), such as long lifetime, narrow emission line, high color purity, and high resistance to photobleaching, have made them widely used in many areas, including but not limited to high-resolution displays, new-generation information technology, optical communication, bioimaging, and therapy. However...
