850-nm Dual-Mode VCSEL Carried 53-Gbps NRZ-OOK Transmission in 100-m Graded-Index Single-Mode Fiber

We demonstrated transmission of 850-nm dual-mode VCSEL carried NRZ-OOK data at 53 Gbit/s over 100 m graded-index single-mode fiber through heterogeneous mode-field mismatched coupling from lensed MMF with 40% efficiency or 4dB loss.
