DSP-free 500-meter Single-mode Fiber Transmission with Record High Bandwidth 1060nm Intra-cavity Metal-aperture Coupled-cavity VCSEL

We demonstrate 500-meter single-mode-fiber transmission using record-breaking 45-GHz modulation bandwidth, single-mode 1060-nm VCSELs with an intra-cavity metal aperture structure. We achieve NRZ-100 Gbps and PAM-180 Gbps data transmission over 500m of SMF with DSP-free receivers.
