This paper reports the feasibility of femtosecond laser etching of microstructures directly onto crystalline N-benzyl-2-methyl-4-nitroaniline (BNA) films grown on glass to realize single crystal BNA waveguides. The threshold fluence has been estimated and fluence range of 318.5-1274 mJ/cm2 at 800 nm is used for ablation. Holes with diameter ranging from 13 to 26¦Ìm and waveguide patterns with width of 100¦Ìm are demonstrated. Grooves with laser transit gap <20¦Ìm is used to form smaller waveguides. Input faces of the waveguides have been simultaneously irradiated with red laser of 630 nm. The optical image of transmission confirms the wave-guiding. This study shows the feasibility of laser-etching waveguides on crystalline BNA films.
