Abstract :
This paper will show how wavelength scale patterning of metallic apertures and gratings on the facet of a Mid-InfraRed Fabry-Perot laser can enhance its performance. In particular improved side mode suppression ratio has been observed and preliminary results for beam shaping and focusing will be shown.
