Judd-Ofelt Analysis of Nd(TTA)3Phen-doped 6-FDA/Epoxy Planar Waveguides
نویسندگان
چکیده
The fluorescent complex Nd(TTA)3Phen (TTA = thenoyltrifluoroacetone, Phen = 1, 10-phenanthroline), was doped into the host material 6-FDA epoxy (6-fluorinated-dianhydride cured epoxy). The room-temperature absorption spectrum of Nd transitions was experimentally obtained, with which the Judd-Ofelt model was applied to determine the Judd-Ofelt parameters. These parameters are used to calculate the emission probabilities of transitions and branching ratios of the Nd from the excited-state F3/2 to lower-lying manifolds. The radiative lifetime of F3/2 was obtained from the emission probabilities. The results of the analysis indicate this Nd (III) complex doped polymer material is promising to be used in planar waveguide lasers and amplifers.

Experimental study of Nd(TTA)3Phen-doped 6-FDA/Epoxy Waveguides
Introduction Lasing and amplification by rare-earth doped polymer materials has been widely investigated [1-2]. In our previous work [3], a Nd(TTA)3phen doped 6-FDA epoxy film was spin-coated on an thermally oxidized wafer. The Judd-Ofelt analysis based on the absorption spectrum shows that this neodymium doped polymer material has a good potential to be used as a planar waveguide in lasers or ...

The emission spectrum of the Nd(TTA)3Phen-doped 6-FDA/Epoxy waveguide was measured at d~fferentpump owers. The result indicates that stimulated emission might take place at 890nm, 1060nm and 1330nm. The luminescent lifetime of this Nd complex doped waveguide was experimentally obtained and shows that this Nd complex is quite promising for amplification. Based on rate equations and experimentall...
