The aberrational characteristics of a concave diffraction grating for
integrated optics have been studied. The quasi-stigmatic region of suc
h gratings is significantly wider than that of corresponding flat grat
ings. The results of calculations for a radiation-output device based
on the proposed grating are given. (C) 1996 The Optical Society of Ame
