Abstract

In future fiber communications systems, efficient mode conversion has the potential to enable improved devices for dispersion compensation and wavelength routing. Previous reports of symmetric-asymmetric mode conversion in circular, multimode optical fibers have shown nonideal spectral characteristics due to polarization dependence and/or mode splitting of nearly degenerate components of the higher order LP₁₁ mode. This work avoids these problems through use of nominally polarization-independent UV-induced phase gratings while exploiting a reflective phase-matching condition that is much less sensitive to the mode splitting of the LP₁₁ mode than prior work
