Abstract
In one example, an optoelectronic assembly may include a laser array, an amplifier array, and a multimode interference coupler optically coupling the laser array and the amplifier array. The laser array may include at least one primary laser and at least one spare laser configured to be activated if the primary laser fails. The amplifier array may include at least two amplifiers configured to amplify optical signals received from the laser array.
