In a recent paper, Burns and co-workers noted that: "In many fiber-optic applications, a definite state of optical polarization is required at the end of a long fiber run. This occurs in coherent communications on mixing with a local oscillator and in fiber sensors to avoid input lead polarization noise and polarization fading." One practical way around this problem is "… the use of depolarized light, which will always remain depolarized independent of fiber birefringence."[1.]
