We present an O-band 400 Gbit/s optical client side Ethernet link with 40 km SSMF reach employing four LAN-WDM lanes, MultiCAP modulation and direct detection.
1060 nm VCSEL-based data transmission over 50 m OM3 MMF at 30 Gbit/s is experimentally demonstrated. A highly-strained bottom-emitting QW VCSEL with p-type modulation doping is used with 3.77 mA bias… (More)
Abstract Vertical Cavity Surface Emitting Lasers (VCSELs) are extremely cost effective, energy efficient optical sources ideal for passive optical access networks. However, wavelength chirp and… (More)
Light beams can carry orbital angular momentum (OAM) associated to the helicity of their phasefronts. These OAM modes can be employed to encode information onto a laser beam for transmitting not only… (More)
This paper reviews and examines several techniques for expanding the carrying capacity of multimode fiber (MMF) using vertical cavity surface emitting lasers (VCSELs). The first approach utilizes… (More)
We demonstrate for the first time optical-domain compensation for coupling between conjugate vortex modes in optical fibers. We introduce a novel method for reconstructing the complex propagation… (More)
Employing MultiCAP signaling, successful 70.4 Gbps transmission over 100 m of OM3 MMF using off-the-shelf 850 nm VCSEL with 10.1 GHz 3-dB bandwidth is experimentally demonstrated indicating the… (More)
In this paper a novel eight-dimensional lattice optimized modulation format, Block Based 8-dimensional/8-level (BB8), is proposed, taking into account the tradeoff between high performance and… (More)
We propose a uniform solution for a future client-side 400 G Ethernet standard based on MultiCAP advanced modulation format, intensity modulation, and direct detection. It employs 4 local area… (More)
Record bit-rate-distance-products of 118.6 and 51.6 Gbps×km were achieved for PAM4 and NRZ transmission over a single OM4 fiber using mode-selective VCSEL. The OMA penalty was 3.1 dB for… (More)
