54 Gbit/s OOK transmission using single‐mode VCSEL up to 2.2 km MMF

Abstract

Successful 54 Gbit/s on-off keying (OOK) transmission over 2.2 km of multimode OM4 fibre is demonstrated. The decisive advantages of the single mode over multimode vertical cavity surface emitting laser (VCSEL) in transmission experiments are shown.

Дизайн и новая функциональность антиволноводных вертикально-излучающих лазеров на длину волны 850 nm

“…Одномодовая генерация была реализована в ВИЛ с диаметром апертуры ∼ 5 µm [8]. С использованием одномодовых ВИЛ была осуществлена безошибочная передача данных со скоростью 54 Gbit/s в формате NRZ (non return to zero) на расстояние 2.2 km [9]. В формате DMT (discrete multitone) продемонстрирована передача данных со скоростью свыше 160 Gbit/s [10].…”

Application of nanophotonics to the next generation of surface-emitting lasers

“…The chromatic dispersion of the MMF presently represents a major challenge limiting the transmission distance for MM VCSEL to 70 and 100 m for OM3 and OM4 fibers, respectively. The only solution to solve the problem is to apply SM 850 nm VCSEL [12] enabling kilometer-scale distances at non-return-to-zero (NRZ) operation at 50 Gb/s [13].…”

“…Frequency and phase remain constant, whereas two different amplitude levels are used to represent the logical values 0 and 1, without a 0 being forced after each 1. Figure 14 shows the effective data rate vs. MMF transmission length for OOK [13,[38][39][40][41][42]. To date, the highest serial data rates demonstrated error-free (BER < 1E-12) using OOK are 71 Gb/s over 7 m [41], 64 Gb/s over 57 m [40], and 60 Gb/s over 107 m [41].…”

“…This approach is studied in Refs [13] and [42], where SM VCSELs are used. Error-free transmission under the consideration of forward error correction (FEC) (BER < 3.8E-3), at an effective data rate of 50 Gb/s over 1 km and 2.2 km MMF, is demonstrated in Refs [13] and [42], respectively.…”
