Channel waveguides based on a polymer, 6-fluorinated-dianhydride/epoxy, which is actively doped with a Nd complex, Nd ( thenoyltrifluoroacetone ) 3 1,10-phenanthroline, are fabricated by a simple and reproducible procedure, spin coating a photodefinable cladding polymer onto a thermally oxidized silicon wafer, photopatterning, backfilling with the active core polymer, and spin coating with an upper cladding layer. Photoluminescence at 1060 nm from the Nd 3 + ions with a lifetime of 130 μ s is observed. Optical gain at 1060 nm is demonstrated in channel waveguides with different Nd 3 + concentrations. By accounting for the waveguide loss of 0.1 dB cm , an internal net gain of 8 dB is demonstrated for a 5.6 - cm -long channel waveguide amplifier. Owing to the nature of the Nd 3 + complex, energy-transfer upconversion affects the gain only at Nd 3 + concentrations above 1 × 10 20 cm 3 .
