Abstract
Edge-emitting laser diodes need astigmatic lenses for collimating and focus
ing the laser beam. The integration of the element on chip offers a more el
egant solution. A grating is etched into the cladding of the planar wavegui
de. Beam forming can be achieved by modulating the grating parameters or by
using a tapered cladding. These two possibilities are discussed in this pa
per.
