1. An optoelectronic assembly comprising:
a single optoelectronic chip comprising:
a laser array including at least one primary laser and at least one spare laser configured to be activated when the primary laser fails, wherein the laser array is configured to transmit optical signals;
an amplifier array including a plurality of amplifiers, each configured to amplify the optical signals received from the laser array and output amplified optical signals; and
a multimode interference (MMI) coupler integral to the single optoelectronic chip, the MMI coupler configured to optically couple the laser array and the amplifier array;
a lens array comprising a plurality of optical lenses disposed adjacent to the amplifier array;
a fiber array comprising a plurality of optical fibers; and
