Abstract
A novel InP-based metal-coated sidewall, hybrid plasmonic multimode interference (MCS-HP-MMI) power splitter has been proposed. Based on two methods of multimode interference self-imaging and Finite Difference Time Domain (FDTD) simulations, a 1*2 MCS-HP-MMI power splitter was numerically analyzed and compared with an HP-MMI power splitter with the same specifications showing 70% reduction in length due to the negative Goos-Hänchen shift in the metal-coated sidewalls of the MCS-HP-MMI power splitter. The width and layer stack specifications of device were optimized using Response Surface Methodology (RSM) to minimize the MMI length and maximize the optical power transmission. A total optical power transmission of 98% was achieved for an MCS-HP-MMI width and length of 662 nm and 190 nm respectively, with wavelength of 1550 nm.
