Silicon will play a practical role in the future of optoelectronic devices. Silicon microelectronics fabrication techniques can be largely exploited to fabricate low-loss and high volume optical devices. In this paper, we report the concept and realization of new two-dimensional 1x16 and 1x32 array waveguide optical power splitters that offer the possibility of a free choice of the output power ration in silicon-on-insulator (SOI). The power splitters compose one dimensional multimode interference (MMI) optical power splitter and multi-layers coupler at wavelength at 155 (mu) m. According to the design, we can reduce the size of SOI power splitters waveguide without increasing propagation loss, efficiently. The results achieved show a remarkable improvement with respect to those of classical MMI power splitters.
