dc.description.abstractSummary form only given. In this work, we develop a surface treatment technique for polishing conical shaped optical fiber deflectors by combining rough mechanical polishing and CO 2 laser treatment (Fig.1). Nanoscale roughness is achieved at conical-shaped 3D surfaces with modulated CO 2 laser treatment. In the literature, there are reports on glass processing by controlling the glass viscosity below the ablation threshold using a CO 2 laser beam. These works provide an improvement of the surface damage resistance in fused silica optics [2], localized repairing of damages in fused silica optics [3], laser polishing of conventional glasses [4] and optical fiber end surfaces [5]. In the literature, it was reported that the bare fiber end could be polished down to 100 nm surface roughness by continuous wave CO 2 laser exposure [6]. In our approach, the modulated CO 2 laser exposure permits the control of thermal loading issue on a thin surface layer and volume melting, surface reflow, deformation of deflector shape could be avoided. A very smooth surface roughness approximately 4.07 nm can be achieved by using this approach. This also provides less-time consuming and laborer independent procedure. In this study, the conical fiber deflector requiring meticulous design and fabrication process was investigated in terms of design, surface roughness profile and light deflection measurements.en_US
