Abstract

This paper presents the fabrication of periodic microholes arrays in BiNbO4 by femtosecond laser ablation. A circular microhole drilling method was introduced. The relationships between microhole appearance and laser microprocessing parameters have been researched in details, and the ablation parameters were optimized to meet the needs of fabrication of periodic microholes. A two-dimensional photonic crystal waveguide consisting of periodic microholes in BiNbO4 was achieved.
