InP/InGaAsP eight-channel multimode interference (MMI) power splitters were successfully demonstrated. Optical transmission characteristics were measured on a 1 × 8 splitter, by means of near-field images with varying wavelength or output power measurement for transverse electrical/transverse magnetic (TE/TM) modes. On the basis of our results, a 1 × 8 MMI power splitter is considered to have good power balance at each channel within a ± 1 dB imbalance in the wavelength range of 60 nm at the centered wavelength of 1540 nm for all incident modes.
