Meniscusletsels bij de hond

Meniscal injuries in the dog are nearly always seen in combination with a cranial cruciate ligament rupture. The medial meniscus is, by far, most commonly affected. Clinical signs indicative for a meniscal tear are severe lameness or a sudden increase of lameness in dogs with a cranial cruciate rupture. Persistent or recurrent lameness after cranial cruciate surgery can equally be caused by a meniscal teat Different imaging techniques can demonstrate a meniscal lesion, or also arthroscopic or direct inspection via arthrotomy may show the lesion. There are several surgical treatment options

Integration of etched facet, electrically pumped, C-band Fabry-Perot lasers on a silicon photonic integrated circuit by transfer printing

We report on the heterogeneous integration of electrically pumped InP Fabry-Perot lasers on a SOI photonic integrated circuit by transfer printing. Transfer printing is a promising micromanipulation technique that allows the heterogeneous integration of optical and electronic components realized on their native substrate onto a target substrate with efficient use of the source material, in a way that can be scaled to parallel manipulation and that allows mixing components from different sources onto the same target. We pre-process transfer printable etched facet Fabry-Perot lasers on their native InP substrate, transfer print them into a trench defined in an SOI photonic chip and post-process the printed lasers on the target substrate. The laser facet is successfully butt-coupled to the photonic circuit using a silicon inverse taper based spot size converter. Milliwatt optical output power coupled to the Si waveguide circuit at 100 mA is demonstrated. (C) 2018 Optical Society of America under the terms of the OSA Open Access Publishing Agreemen
