抄録
Photon-pair generation based on optical parametric down-conversion has attracted for the application as a light source for quantum information. Highly efficient wavelength-conversion devices require a polarity-inversion structure when using nitride semiconductors. A transverse quasi-phase-matching (QPM) polarity-inverted GaN bilayer channel waveguide device is suitable for efficient wavelength conversion. This study designed a cross-section device to satisfy the modal dispersion phase-matching condition between the TM₀₂ mode pump light and the TM₀₀ mode signal/idler light. Moreover, an AlN oxidation interlayer fabricates the Ga-polar/N-polar (+c/−c) GaN layers via metalorganic vapor-phase epitaxy (MOVPE). A 145 nm thick film layer with a macro-step-free surface is grown by optimizing the −c-GaN growth conditions and reducing the substrate off-angle to 0.2°. Next, the AlN layer is oxidized in an electric furnace and MOVPE is used to regrow a 1500 nm thick +c-GaN layer. A macrosteps-free surface can be achieved by reducing the off-angle to 0.2° and optimizing the −c-GaN growth conditions to avoid hillock formation. These results pave the way for improving the efficiency of GaN transverse QPM wavelength-conversion devices.
