In this paper, we study an original strategy to generate an infrared waveband microlaser by an integrated III–V-nanowire (NW)-based photonic array for on-chip interconnects. The optical modes of the III–V-NW-based photonic array are investigated for utilization as an all-in-one gain medium, waveguide, and cavity. Adequate designs of periodic arrays of InP NWs with different polarization TM and TE modes are studied by 3D electromagnetic simulation finite difference time domain to optimize the res
