Galby, Esther ; T. Lima, Paloma ; Paulusma, Daniël ; Ries, Bernard

In: Information procesing letters, 2019, vol. 146, p. 39-43

A graph is H-free if it does not contain an induced subgraph isomorphic to H. For every integer k and every graph H, we determine the computational complexity of k-Edge Colouring for H-free graphs.

Measurement of the linewidth enhancement factor of singlemode room temperature continuous wave quantum cascade lasers

Aellen, Thierry ; Aebi, Philipp (Dir.)

Thèse de doctorat : Université de Neuchâtel, 2008.

The invention of the laser source in 1960 has led to a wide range of applications showing a widespread impact in every aspect of our today life, including for example hospital, factory or simply at home. In particular, recent developments originating from the compact, highly efficient and common semiconductor lasers that are simply supplied by an electrical current. The diode coherent light...
