In this paper, we present the design, manufacturing, characterization, and analysis of the coupling ratio spectral response for multimode interference couplers in silicon-on-insulator (SOI) technology. The couplers were designed using a Si rib waveguide with SiO2 cladding, on a regular 220 nm film and 2μm buried oxide SOI wafer. A set of eight different… CONTINUE READING
