Broadband single-mode operation of standard optical fibers by using a sub-wavelength optical wire filter
We report the use of a sub-wavelength optical wire (SOW) with a specifically designed transition region as an efficient tool to filter higher order modes in multimode waveguides. Higher-order modes are effectively suppressed by controlling the transition taper profile and the diameter of the sub-wav...
