In this paper, we report the first graded index (GRIN) polymer waveguide amplifier working at 1.06 micrometers wavelength using Nd:photolime gel material combination. 8.5 dB gain was observed using a 2.2 cm waveguide length with Nd+++ concentration of 1.03 (DOT) 1020/cm3. A tunable Ti:Sapphire laser was used as a pumping source. The success of this demonstration together with the previously reported results on GRIN polymer passive and active devices, provide us the full capability of integrating a monolithic polymer- based integrated optical circuit.
