Polymer-based, 6-FDA/epoxy channel waveguides doped with a Nd complex, Nd(TTA) 3 phen, are fabricated by a simple and reproducible procedure mainly based on spin coating and photo-definition. Photoluminescence at 1060 nm from the Nd 3+ ions with a lifetime of 130 μs is observed. Optical gain at 1060 nm is demonstrated in channel waveguides with different Nd 3+ concentrations. By accounting for the waveguide loss, an internal net gain of 8 dB is demonstrated for a 5.6-cm-long channel waveguide
