ABSTRACT
Neodymium-doped polyimide waveguides were studied for optical amplifier applications. Photoluminescence at 890 nm, 1.06 μm, and 1.33 μm from neodymium ions in the polymer matrix was observed. Optical gain of about 8 dB was measured at 1.06 μm in a 5-cm-long multimode channel waveguide. Phase separation was observed in the doped polyimide. Large scattering losses in the waveguides due to the phase separation were reduced by planarizing the layer of doped polyimide with another layer of undoped polyimide. Such a waveguide amplifier has potential applications in lossless splitters, lossless fiber, and waveguide systems with large fanout. © 2000 American Institute of Physics.

    Contrary to most Pr3+-doped materials, Pr3+-doped BaGd2(MoO4)4 crystals do not generate the 1320 nm photoluminescence, which is used as an amplifier for O-band optical communications. However, it is found to generate a broad emission band in the wavelength region of 1400-1550 nm with full-width...
