中文摘要	mmi coupler with large cross section has low coupling loss between the device and fiber. however, large chip area is required. recently proposed n x n tapered mmi coupler shows a substantial reduction in device geometry. no such kind of devices with n > 2 has yet been realized up to now. the authors have demonstrated a 4 x 4 parabolically tapered mmi coupler with large cross section that can match the sm fiber in silicon-on-insulator (soi) technology. the device exhibits a minimum uniformity of 0.36 db and excess loss of 3.7 db, it represents a key component for realization of mmi-based silicon integrated optical circuit technology.
