Abstract
A new type of single mode fiber-optic depolarizer is proposed and demonstrated. The new depolarizer consists of a Mach-Zehnder interferometer with one arm used as a delay line with respect to the other. Light having a 100-MHz spectral width, for example, can be depolarized with high coupling efficiency to single mode fibers by using a polarization-maintaining fiber-delay line of a few meters in length.
