We present a CMOS compatible mass manufacturable, compact Si/SiO2 multilayer GRIN lens mode size converter from standard single mode fiber to 300nm-thick Si waveguide. The fiber-to-GRIN lens coupling loss is 2.6 ± 0.3dB (coupling efficiency: 51~60%) with optimized focal length of 11.6~11.8μm and Si/SiO2 multilayer thickness of 7.4μm.
