Abstract
Grating-coupled surface-emitting semiconductor lasers have been integrated with focusing and spot array generating diffractive beam-forming elements. The lasers have an unstable resonator producing a 160-/spl mu/m-wide single spatial mode. The area of the outcoupler element is 160 /spl mu/m/spl times/240 /spl mu/m. For an outcoupler focusing at 500 /spl mu/m above the surface the spot size is 9 /spl mu/m/spl times/17 /spl mu/m The spot size is primarily limited by aberrations in the wavefront of the guided mode.
