Abstract
The planar and channel waveguides were fabricated by C ion implantation on
Nd:SrGdGa<sub>3</sub>O<sub>7</sub> crystal respectively. The guided modes and optical
propagation properties were investigated by waveguide coupling method, and the
simulation of the light propagation process was performed simultaneously for comparison.
The propagation losses of planar and channel waveguides were 0.84 dB/cm and 0.5 dB/cm,
respectively, which were measured by end-face coupling equipment. The confocal
microfluorescence investigation was used to observe the influence of the C ion
implantation process on the Nd ions properties. It shows that there are merits about the
relative low loss and the good reservation of Nd ions fluorescence properties in the
C-ion-implanted waveguide. Thus, this waveguide could be a very promising candidate for
integrated optical device.
