Resumen
We report on the fabrication and characterization of femtosecond
laser micromachined depressed cladding waveguides in lithium niobate
crystal. The cladding structures support two-dimensional guidance of light
from the visible to the mid-infrared spectral regimes. Particularly, singlemode
propagation of light at a wavelength of 4 μm has been achieved for
the waveguides with diameter of 50 μm. It is also found that the thermal
annealing treatment reduces the propagation loss lower than 0.5 dB/cm at
1.064 μm, exhibiting good transmission properties for photonic
applications.
