Uniform performance of high-efficiency room-temperature GaInAsSb/GaSb photodiodes for 1.75 < lambda < 2.2 mum.
A group of 126 experimental, packaged, backilluminated, 1.75-2.2-microm wavelength, GaInAsSb mesa (~85-microm diameter) photodetectors have been assembled and evaluated. Average room-temperature properties were peak quantum efficiency, 86%; zero-bias capacitance, 3.9 pF; dark current at -0.5-V bias, 7.4 microA.
2.2 μm GaInAsSb/AlGaAsSb injection lasers with low threshold current density
Double heterostructure 2.2 μm wavelength lasers were fabricated from Ga0.84In0.16As0.15Sb0.85/ AlxGa1−xAs0.04Sb0.96 wafers grown by liquid phase epitaxy. These structures were grown with Al‐rich confinement layers (x=0.4) for optical confinement and thin intermediate cladding layers (x=0.34) to relieve the strain resulting from the lattice mismatch of the Al‐rich confinement layers with respect to the substrate and the active layer. A threshold current density as low as 1.7 kA/cm2 was obtained at room temperature.
MT and the Swiss language service providers: an analysis and training perspective
Switzerland is perceived as a highly multilingual country, with four national languages and a solid translation tradition in official, administrative and corporate settings, now even extended to include English. A research case study was set up to investigate the understanding and use of translation and language technologies by Swiss language service providers. This paper highlights some findings, particularly focusing upon the issue of translation automation processes in multilingual documentation production, with a view not only to spot preconceptions or knowledge gaps about MT, but also to 
suggest some training principles. We will argue that training activities ought to present MT systems as 
key aiding components of translator workbenches and, their output, as a valid linguistic resource for further human refining, if necessary. Moreover, in line with the idea that MT can be part and parcel of multilingual content production cycles, we will look at the interaction of MT with controlled language, CAT tools and terminology work. In sum, we will make explicit the usefulness of MT against the 
widespread prejudice that investing in MT does not return any benefits given the ‘low and hilarious quality of its output’, as quoted by most of the interviewees of our case study.
