New type of optical fiber with an extremely large core diameter has been developed to preserve the coherent properties of light. This study can help in constructing high-power pulsed fiber lasers and amplifiers and polarization-sensitive sensors. According to the researchers, the geometric length of the path traveled by light through the fiber at which the oscillations of the two different polarizations are in antiphase depends on the fiber core diameter. It decreases as the diameter is increased. This length, known as the polarization beat length, corresponds to one complete rotation of the linear polarization state in the fiber. In other words, if you launch linearly polarized light into a fiber, it will be linearly polarized again after traveling precisely this distance. The ability to measure this parameter is in itself evidence of the fact that the polarization state in the fiber is preserved. Read more about this news or go back to the original post here.
