TL;DR: In this paper, the authors reported on optical waveguide fabrication in a spinel MgGa 2 O 4 crystal by 60 MeV carbon ion implantation at a fluence of 2 × 10 15 ions/cm 2 for the first time to their knowledge.
Abstract: We report on optical waveguide fabrication in a spinel MgGa 2 O 4 crystal by 60 MeV carbon ion implantation at a fluence of 2 × 10 15 ions/cm 2 for the first time to our knowledge The MgGa 2 O 4 crystal was grown by the floating zone method The refractive index profile reconstructed by reflectivity calculation method showed that the MgGa 2 O 4 waveguide is a typical barrier waveguide The typical barrier-shaped refractive index profile is attributed mainly to the nuclear energy deposition of the incident carbon ions into the MgGa 2 O 4 crystal By performing end-coupling measurements and using the beam propagation method (BPM) for the analysis of the observed modes, it can be concluded that the modes can be confined inside the waveguide
