Abstract
Neodymium-doped polyimide waveguides were studied for optical amplifier app lications. Photoluminescence at 890 nm, 1.06 mu m, and 1.33 mu m from neody mium ions in the polymer matrix was observed. Optical gain of about 8 dB wa s measured at 1.06 mu m in a 5-cm-long multimode channel waveguide. Phase s eparation was observed in the doped polyimide. Large scattering losses in t he waveguides due to the phase separation were reduced by planarizing the l ayer of doped polyimide with another layer of undoped polyimide. Such a wav eguide amplifier has potential applications in lossless splitters, lossless fiber, and waveguide systems with large fanout. (C) 2000 American Institut e of Physics. [S0003-6951(00)02835-7].
