Abstract
The authors demonstrate a 3 dB 2×2 parabolically tapered multimode interference (MMI) coupler with a large cross-section and space between the different ports using silicon-on-insulator technology. The device exhibits a uniformity of <0.8 dB and can be used in the realisation of an MMI-based optical switch with a high extinction ratio
