We report a new technique to apply strain to a vertical-cavity surface
-emitting semiconductor laser. This has allowed us to study the relati
on between strain and birefringence. We have found that the correspond
ing tensor is anisotropic, with a measured anisotropy 2p(44)/(p(11)-p(
12)) = 4.7 +/- 0.6. This anisotropy explains the natural preference of
the polarization for the [110]/[1(1) over bar0$] axes. (C) 1996 Ameri
