Abstract

By directly writing waveguides inside bulk erbium-doped oxyfluoride silicate glass using a focused femtosecond pulse train, we demonstrate the potential for the fabrication of especially broadband, compact telecommunications optical amplifiers operating in the c -band (1529-1561 nm). Characterization results include coupling losses to single-mode fiber, waveguide losses, and gain measurements. Clear relationships between the fabrication pulse energy and the waveguide losses and coupling losses are also established. © 2005 American Institute of Physics.
