Raman scattering and optical depolarization measurements on K1−xLixTa1−yNByO3 with y ⩽ 0.028 and x ⩽ 0.06 show that lithium impurities destabilize the niobium-induced rhombohedral ferroelectric phase. With increasing x the phase transition is

The performance characteristics of any multimode fiber optic component, be it connector, coupler, multiplexer, or switch, are dependent on the modal intensity profile at the input of the device. It follows that any component that restructures the mod
