  • Ahlsén, Bertil, et al. (författare)
  • Ombyggnad Torslanda
  • 1990
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Consumer report for the company in question (the Volvo Automobile Company and the Volvo Torslanda plant) which is financed by the company and partly also by a research foundation. It is a matter of a work that in this particular case were carried out during nine years in a number of experimental workshops located outside the Chalmers University of Technology. These workshops were financed by the Volvo Automobile and Truck companies. This achievement, as the final contribution to the Swedish automotive industry after having already treated this research field/problem area for more than two decades before this particular period if time (involving several junior and senior research competencies, as well as industrial and governmental foundings).

  • DFB laser with nonuniform coupling coefficient realized by double-layer buried grating
  • 1993
  • Ingår i: IEEE Photonics Technology Letters. - : Institute of Electrical and Electronics Engineers (IEEE). - 1041-1135 .- 1941-0174. ; 5, s. 1128-1131
  • Tidskriftsartikel (refereegranskat)abstract
    • A technique for the realization of a nonuniform grating coupling coefficient kappa , and its implementation in distributed-feedback (DFB) lasers is presented. This technique, which is an extension of the buried-grating concept, offers precise control of the coupling coefficient and enables a kappa -ratio greater than 10. DFB lasers with an asymmetric kappa -variation have been fabricated using this method. A front-to-rear facet output power ratio close to five was obtained, qualitatively in agreement with simulations.<>
