On optical activity of Er3+ ions in Si-rich SiO2 waveguides
Photoluminescence spectroscopy was used to explore the optical activity of Er3+ ions in Si-rich SiO2 waveguides prepared by ion implantation. Measurements were performed for a series of materials characterized by different Si excess levels, Er concentrations, and annealing temperatures. The highest fraction of optically active Er3+ ions which can be efficiently activated by nonresonant pumping ...
متن کاملPlanar waveguides in ZBLAN fabricated by He ion implantation
Single and double planar waveguides were fabricated by 2 MeV and 4 MeV He implantation in ZBLAN. Calculation of ion implantation parameters, cut-off wavelength measurement and near-field detection indicate that ∆n is negative, typically -1x10. 1999 Optical Society of America OCIS codes: (130.3130) Integrated optics materials; (230.7390) Waveguides, planar.
متن کاملSi-CMOS-compatible lift-off fabrication of low-loss planar chalcogenide waveguides.
We demonstrate, for the first time to the best of our knowledge, low-loss, Si-CMOS-compatible fabrication of single-mode chalcogenide strip waveguides. As a novel route of chalcogenide glass film patterning, lift-off allows several benefits: leverage with Si-CMOS process compatibility; ability to fabricate single-mode waveguides with core sizes down to submicron range; and reduced sidewall roug...
متن کاملUltra-low-loss Ta2O5-core/SiO2-clad planar waveguides on Si substrates
An increasing number of systems and applications depend on photonics for transmission and signal processing. This includes data centers, communications systems, environmental sensing, radar, lidar, and microwave signal generation. Such systems increasingly rely on monolithic integration of traditionally bulk optical components onto the chip scale to significantly reduce power and cost while sim...
متن کاملCuts in Directed Planar Networks by Parallel C Omput at Ions
We reduce the exponent to 3 in the case when the network is embedded in the plane beforehand and to 4 otherwise. The reader is supposed to be familiar with graphs, planar graphs, multigraphs and so on (see [1]). We use the well-known method in a similar way as in [4] which consists in the fact that the problem of finding minimum cuts in a network can be reduced to the shortest path problem in i...
