title: Birefringence of optical fiber pressed into a V groove.
abstract: When an optical fiber is pressed into a V groove, the stress-induced birefringence in the fiber depends on the groove angle 2gamma. Ignoring friction, this birefringence should vanish at 2gamma = 60 degrees . In practice, friction is dominant, precluding the possibility of birefringence-free holding of the fiber by clamping it into a V groove.
