Tantalum pentoxide (Ta2O5) is a promising high index material for dense photonic circuits, with the incorporation of gain substantially increasing its potential functionality. Diode-pumped laser action is demonstrated in 2.3-cm-long Ta2O5 rib waveguides doped with 2.7 × 1020 erbium ions/cm3, which were fabricated by magnetron sputtering on an oxidized silicon wafer. Lasing was observed at wavelengths between 1558 and 1562 nm with a launched diode pump power threshold of 14 mW.

Abstract
Tantalum pentoxide (Ta2O5) is a promising high index material for dense photonic circuits, with the incorporation of gain substantially increasing its potential functionality. Diode-pumped laser action is demonstrated in 2.3-cm-long Ta2O5 rib waveguides doped with 2.7 × 1020 erbium ions/cm3, which were fabricated by magnetron sputtering on an oxidized silicon wafer. Lasing was observed at wavelengths between 1558 and 1562 nm with a launched diode pump power threshold of 14 mW.File in questo prodotto:
