We report on fabrication of tubular optical waveguides buried in ZBLAN glassbased on transverse femtosecond laser direct writing. Irradiation in ZBLAN withfocused femtosecond laser pulses leads to decrease of refractive index in themodified region. Tubular optical waveguides of variable mode areas arefabricated by forming the four sides of the cladding with slit-shapedfemtosecond laser pulses, ensuring single mode waveguiding with a mode fielddimension as small as ~ 4 {\mu}m.
