In: 2019 IEEE Photonics Conference, IPC 2019 - Proceedings.
-
Conference paper (peer-reviewed)abstract
- We experimentally demonstrate 90Gbps error-free PAM-2 transmission and 102Gbps PAM-2 transmission below the KP4 FEC threshold over 50m OM5 multimode fiber at 850nm The link includes unpackaged 850nm VCSELs with 26GHz bandwidth and implements limited linear equalization and raised cosine pulse shaping.

Error-Free 100Gbps PAM-4 Transmission over 100m OM5 MMF using 1060nm VCSELs
- 2019
-
In: Optics InfoBase Conference Papers. - 2162-2701. ; Part F160-OFC 2019
-
Conference paper (peer-reviewed)abstract
- We experimentally demonstrate error-free (BER <10 -12 ) rates beyond 100Gbps over 100m OM5 using unpackaged 1060nm VCSELs. Power penalties of PAM-2/PAM-4 are examined demonstrating OM5 fiber capacity to support wavelengths to 1060nm with only transmitter equalization.

Error-Free 100Gbps PAM-4 Transmission over 100m Wideband Fiber using 850nm VCSELs
- 2017
-
In: European Conference on Optical Communication, ECOC. ; 2017-September, s. 1-3
-
Conference paper (peer-reviewed)abstract
- We experimentally demonstrate error-free rates beyond 100Gbps over 100m WBMMF. Power penalties and maximum data rates of PAM-2 and PAM-4 using shaped and unshaped pulses were studied. The link includes unpackaged 850nm VCSELs with different apertures and only transmitter equalization.

Error-free 850nm to 1060nm VCSEL links: Feasibility of 400Gbps and 800Gbps 8λ-SWDM
- 2019
-
In: IET Conference Publications. - 9781839530074
-
Conference paper (peer-reviewed)abstract
- We demonstrate effective transmitter equalization for 850nm, 980nm, and 1060nm VCSELs and 100m OM5 links enabling 78Gbps PAM-2 and >100Gbps PAM-4 100m error free links. Extracted link penalties reveal net fibre dispersion and RIN enhancement create small to negligible power penalties for all wavelengths.

Optimum VCSEL Apertures for High-Speed Multimode Fiber Links
- 2018
-
In: 2018 Optical Fiber Communications Conference and Exposition, OFC 2018 - Proceedings. - 9781943580385
-
Conference paper (peer-reviewed)abstract
- Cross-correlations of VCSEL transverse mode groups with different apertures are used to predict dispersion dependent RIN. Experiments with wideband multimode fiber confirm the noise enhancement dependence on aperture, which increases with fewer mode VCSELs.

Power Efficient Modulation Formats for Error-Free VeSEL MMF Links
- 2018
-
In: European Conference on Optical Communication, ECOC. ; 2018-September
-
Conference paper (peer-reviewed)abstract
- We determine the most efficient modulation format for deployable 25Gbps, 50Gbps, and 100Gbps links. Error-free performance was tested and compared for PAM-2, PAM-4, and duobinary until maximum data rates were achieved. The link includes unpackaged 850nm VCSELs and transmitter equalization.

Polybinary Coding for Low Complexity High Speed Error-Free VCSEL-MMF Links
- 2017
-
In: European Conference on Optical Communication, ECOC.
-
Conference paper (peer-reviewed)abstract
- We demonstrate and analyze polybinary signaling as a low complexity alternative to PAM-4 for achieving higher bitrates in VCSEL-MMF links. Experimental results demonstrate that duobinary and polybinary-3 achieves similar performance as PAM-4 through 105m of wideband fiber at 10e-12 BER.
