Waveguides were femtosecond laser-written in Er:Yb-doped phospho-tellurite glass yielding internal gain across an unprecedented 100-nm bandwidth covering the whole C+L communications bands. The waveguide modes were highly confined, showing promise for improved photonic integration.

Abstract
Waveguides were femtosecond laser-written in Er:Yb-doped phospho-tellurite glass yielding internal gain across an unprecedented 100-nm bandwidth covering the whole C+L communications bands. The waveguide modes were highly confined, showing promise for improved photonic integration.File in questo prodotto:
