摘 要: 通过实验研究,对光束在晶体平行于c轴的界面发生全内反射时入射光与反射光在出射面形成的干涉光栅施加外电场,首次观察到由纵向调制不稳定性(modulation instability, MI)导致的铌酸钡锶(strontium barium niobate, SBN)晶体界面形成二维孤子阵列。o光和e光形成二维点阵所需的外加电场强度大小以及达到稳定所需的时间不同。e光入射时条纹分裂为细丝,而o光入射时条纹分裂为孤子列。
关 键 词: 光学;纵向调制不稳定性;晶体界面;二维阵列

Abstract: In this paper, an electric field was applied on the grating formed by incident beam and reflected beam on the output face when total internal reflection of beam occurred on the crystal surface paralleled with the c-axis. For the first time, we observed two-dimensional surface soliton array due to longitudinal modulational instability (MI) at the interface of strontium barium niobate(SBN) and air. The applied electric field intensity and the stability time needed to form the 2D surface solitons array by ordinary and extraordinary beam were different. The patterns broke into filaments when the extraordinary beam was incident, while the patterns broke into the solitons arrays when the ordinary beam was incident.
Key words: optics; longitudinal modulational instability; grain boundary; two-dimensional array
