A 0.98 μm laser-diode-pumped waveguide amplifier is successfully realised by using an Er-doped silica-based planar lightwave circuit. The highest signal gain of 9.4 dB is achieved at a signal wavelength of 1.533 μm with a pump power of 99 mW, using a highly efficient erbium-doped waveguide and high power laser diodes.
