Abstract :
Summary from only given. We propose and demonstrate a novel buried oxide grating structure formed by selectively-oxidized AlGaAs layers grown on nonplanar substrates. The gratings provide a very wide stopband due to the large refractive index difference between the oxidized and non-oxidized AlGaAs. Potential applications include microcavity DFB lasers, tunable lasers, and various microstructure waveguide devices.
