Correlation of Substitutional Hydrogen to Refractive Index Profiles in Annealed Proton-Exchanged Z- and X-Cut LiNbO3

Abstract

The goal of this project was to investigate waveguiding in optoelectronic crystals. Studies of the correlation between hydrogen (H) concentration and the extraordinary refractive index n sub e in proton-exchanged lithium niobate (LiNbO3) were resolved by partitioning the total H into optically active substitutional H and optically inactive interstitial H. These results were summarized in two publications: Applied Physics Letters, 63, 718 (1993) and Journal of Applied Physics, 77, 2697 (1995). Studies were initiated on the group III nitrides. These studies included the investigation of the surface properties of GaN, the absorption coefficient in GaN, and the emission properties of blue light-emitting diodes. The results on GaN were summarized in three publications: Applied Physics Letters 68, 1850 (1996), Applied Physics Letters 68, 2867 (1996), and Applied Physics Letters 71, 2572 (1997).
