Paper Abstract

A theoretical and experiment analysis of two-step ion-exchanged glass optical power splitter is reported. In order to facilitate quantitative analysis, we propose the rational model of physics for a 1×4 S-branch power splitter in glass. These surface half-round channel waveguides are fabricated by first performing a thermal exchange in Tl2SO4 through a mask patterned on the glass surface. The channel waveguides are then buried by second thermal Na+ exchange, unmasked ion exchange, in melt NaNO3. A buried optical power splitter of low insertion loss and uniformity loss has been realized.
