Demonstration of optical gain at 1550 nm in an Er 3+ -Yb 3+ co-doped phosphate planar waveguide under commercial and convenient LED pumping

A 980 nm semiconductor laser is always selected as the pump source for erbium-ytterbium co-doped optical waveguide amplifiers. In this work, two low-cost blue-violet LEDs, rather than an expensive 980 nm laser, were used to pump an Er -Yb co-doped phosphate planar waveguide. When the signal power wa...
