Low-Power Data Center Transponders Enabled by Micrometer-scale Plasmonic Modulators (W1D.1) - Invited
08:00 AM - 08:30 AM
Plasmonic modulators allow for high-speed data modulation beyond 200GBd at the micrometer-scale and low driving voltages below 700mV. The compact footprint enables dense integration and makes plasmonic modulators a promising solution for next-generation optical interconnects.

Distortion-aware 2D soft decision for VCSEL-MMF optical PAM interconnection (W1D.2)
08:30 AM - 08:45 AM
A distortion-aware 2D soft decision method of PAM signals have been proposed for VCSEL-MMF interconnection system. Improvements and application potential have been experimentally investigated on a 112-Gbps optical PAM-4/8 system using a multimode VCSEL.

168Gbps PAM-4 Multimode Fiber Transmission through 50m using 28GHz 850nm Multimode VCSELs (W1D.3)
08:45 AM - 09:00 AM
We experimentally demonstrate PAM-4 data rates beyond 160Gbps over 50m OM5 using unpackaged 850nm VCSELs. Power penalties of PAM-4 are examined demonstrating maximum data rates, with and without FEC, over 50m and 100m of fiber.

4×56-GBaud PAM-4 SDM Transmission Over 5.9-km 125-μm-Cladding MCF Using III-V-on-Si DMLs (W1D.4)
09:00 AM - 09:15 AM
We demonstrate 4×56-GBaud PAM-4 signals over 125-μm-cladding, 4-core fiber by simultaneous, direct modulation of four 1.3-μm membrane III-V-on-silicon lasers, each requiring <25-mWatts (@12 mA). A reach extension of ~15x is achieved compared to previous works.

1.12 Tbit/s fiber vector eigenmode multiplexing transmission over 5-km FMF with Kramers-Kronig receiver (W1D.5)
09:15 AM - 09:30 AM
We demonstrate a 1.12 Tb/s MIMO-free vector eigenmode multiplexed signal transmission over 5-km 4-mode few-mode-fiber using HE11 and EH11 vector modes, 5 wavelengths and 28 GBaud 16-QAM signal with direct-detection Kramers-Kronig receiver.

Single λ 500-Gbit/s PAM Signal Transmission for Data Center Interconnect Utilizing Mode Division Multiplexing (W1D.6)
09:30 AM - 09:45 AM
Single wavelength 502.5-Gbit/s MDM-PAM-6 signal transmission over 20-m OM2 fiber with BER below HD-FEC threshold (3.8×10-3) is demonstrated for 400-G Data Center Interconnect without DSP for mode de-multiplexing. This scheme shows good potential for future 800-G/1.6-T DCI.
