| Abstract: | The first integrated optical amplifying acoustically tunable wavelength filter in Er-doped LiNbO3 is reported. At the signal wavelength of λs=1531 nm a maximum gain of 4.8 dB has been obtained with a coupled pump power of 160 mW (λp =1484 nm). Lossless signal transmittance has been achieved with a pump power as low as 13.5 mW for λs>1561 nm |
