Abstract
Ion-exchange technology is low cost, and can fabricate waveguide well coupled with fiber. It is a good choice to manufacture passive device applied in the Passive Optic Net(PON). In this paper first we get surface waveguide using Ag+-Na+ ion-exchange method, then we apply 400V electric-field on the glass wafer to get waveguide buried, the whole process is at 300ºC.The width of final single-mode waveguide is 8.5μm, depth from the glass surface is 18μm. It has low coupling loss with fiber. Insertion loss of 2cm long straight waveguide can be lower than 0.6dB. Propagation loss of straight waveguide can be lower than 0.2 dB/cm. We repeat this process to manufacture 1× 8 optical power splitter. Under the wavelength 1310nm,1490nm and 1550nm, the mean value of insertion loss is 9.8dB, the maximum is 10.19dB, the minimum is 9.31dB, the maximum of PDL is 0.04dB.
