| Outline of Final Research Achievements |
For obtaining wavelength-converted light waves with higher-oder transverse modes, we have successfully fabricated GaAs/AlGaAs two-dimensional quadratic nonlinear photonic crystal waveguides, which are composed of inversion-stacked periodically-inverted waveguide, by using surface-activation bonding technique. This result will lead to the basis of the fabrication of three-dimensional quadratic nonlinear photonic crystal waveguides.
Furthermore, we proposed high efficient wavelength conversion devices utilizing optical gain based on stimulated interband emission due to current injection to compensate propagation losses, and succeeded in fabricating AlGaAs pin heterojuncition diodes on periodically-inverted GaAs substrates. This will open up novel wavelength conversion devices utilizing current-injection induced optical gain.
