摘要:

A new optical waveguide of a single‐crystal Sr2Nb2O7film grown onto ab‐plate Sr2Ta2O7substrate by rf sputtering is reported. Waveguide propagation loss was 7.6 dB/cm for the TE0mode at 6328 A˚. An increased oxygen concentration in the sputtering gas is effective in lowering the optical waveguide propagation loss.
