Efficient Optical Waveguiding Enabled by Focused Proton Beam Writing in Nd:YCOB Crystal
We report on microfabrication and optical characterization of buried channel waveguides defined in Nd:YCOB crystal by focused proton beam writing (PBW). In the fabrication process, the focused proton beam irradiation creates a local material modification region with geometrically symmetric positive...
