Abstract

In this paper, we designed a mode size converter to reduce coupling loss between optical waveguide and single mode fiber. The proposed mode converter is composed of periodically segmented tapered waveguide to achieve small size and easy fabrication. For the optimally designed mode size converter at 1550nm, the taper length is 500ߦ, the segmentation period 5ߦ, the waveguide width of fiber contact section 1.3ߦ, and duty cycle 0.95. The coupling loss of the optimized mode size converter is 0.33dB/point, which is 1.27dB/point lower than that without the mode size converter.
