Abstract

We report the fabrication and packaging of 1 by 8 power splitter on BK-7 glass. The single mode waveguide structures at 1.31 and 1.55 micrometers have been fabricated using K⁺- Ag⁺-Na⁺ ion exchange at 340 degrees followed by the reverse ion exchange at the same temperature. The power splitter is first tested on the optical test bench and then fiber pigtailed using an automated alignment system and packaged in a compact housing. The total insertion loss for 1 by 8 power splitter after packaging is 5.6 dB at 1.31 micrometers and 4.8 dB at 1.55 micrometers wavelength. The uniformity of power in the output ports is < 1.5 dB while the directivity is measured to be > 40 dB.
