摘要

We have designed, epitaxy-grown, nano-fabricated and investigated several different-type InAs/InP quantum dash / dot (QD) multi-wavelength lasers (MWLs) around 1550 nm with very low relative intensity noise and ultra-narrow optical linewidth. By using those QD MWLs, we have experimentally demonstrated optical-heterodyne millimeter-wave-over-fiber fronthaul systems with high data throughput wireless links through 25- and 50-km single mode fiber featuring a free-space data capacity of up to 36 Gb/s, which has clearly indicated that the developed QD MWLs are critical building blocks of achieving low-noise millimeter-wave (mmW) signal generation and transmission for 5G & beyond wireless networks.
