The optical behavior of polycrystalline SILSO silicon wafers with a me
chanically V-grooved surface has been studied between 300 and 1500 nm.
The texturization was carried out by a conventional dicing saw using
beveled blades. For a 35-degrees V-grooved surface and a nonmetallized
backside the optical path length in the weakly absorbing part of the
spectrum (1100-1200 nm) was found to be enhanced by a factor of 33 as
compared to a nongrooved wafer. The enhanced reflectance in the nonabs
orbing spectral region for the former is analyzed and explained. The d
ifferent loss contributions due to a nonideal grooved structure are di
scussed.
