Abstract:By exploiting large transition cross-sections, high dopant concentration, and strong light confinement, a gain of 950 dB/cm is demonstrated in a large-refractive-index-contrast KGdxLu1-x(WO4)2:Yb3+ channel waveguide, representing a two-orders-of-magnitude improvement over previous results in rare-earth-ion-doped materials.
