A multimode interference coupler is proposed for pumping two erbium-doped waveguide amplifiers from a single 980 nm pump channel. Simulations predict that a device less than 2500 microm long can be made with signal and pump power losses of 0.28 dB and 0.63 dB respectively. The calculated 1 dB excess loss bandwidth of the device is 57 nm.
