A discussion about a coupler of a InP active component on a silicon-on-insulator (SOI) wafer is presented for applications in optical interconnects. A model for the design and evaluation of the coupler is developed using a coupling length based a model solver, the model solver is specifically suited for high index contrast waveguides with small area, which show more accurate for compact integrated optical devices. The photonic coupler is fabricated using microelectronics equipment for compatibility towards future generation electronic integrated circuit processing. Measured coupler efficiency is 65% to valid our model. This will be helpful for the design of InP active components.
