Abstract
We report on the fabrication of channel waveguides in bismuth germanate (BGO) crystal using focused ion-beam writing. 1 and 2 MeV He+ ions with different fluences are utilized to directly write waveguides in BGO crystal. The guiding properties of the BGO waveguides are explored at the wavelengths of 632.8 nm, 1.31  μm and 1.55  μm, showing that the channel waveguides support light guidance from visible to telecommunication bands along both transverse-electric and transverse-magnetic polarizations.
