摘要
Tantalum pentoxide (Ta(2)O(5)) 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 Ta(2)O(5) rib waveguides doped with 2.7 x 10(20) erbium ions/cm(3), 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.
