Transmission of 112 Gb/s PM-QPSK signals over up to 635 km of multimode optical fiber.

We investigate transmission of 112 Gb/s PM-QPSK signals over 50 μm core diameter OM3 multimode fiber using the center launch approach. We demonstrate successful transmission of 16 DWDM channels over a distance of 635 km.

Multicore fiber for optical interconnect applications

We propose multicore fibers with linear array configurations for optical interconnect applications. We discuss fiber design considerations and present actual 1×4 and 2×4 fiber results.

Experimental observation of orthogonally polarized time-delayed optical soliton trapping in birefringent fibers

Propagation of two orthogonally polarized time-delayed optical solitons in low-birefringence optical fiber is studied experimentally. We demonstrate soliton trapping and collisions and also the ability to control the separation and shape of soliton pulses by varying the power at the input of the fiber.

Multicore optical fiber and connectors for high bandwidth density, short reach optical links

Multicore fiber technology can play a key role in very high bandwidth density optical interconnects that will be needed for short range communications in next-generation data centers and high performance computers.

Space Division Multiplexing in Short Reach Optical Interconnects

Many technical capabilities of space division multiplexed systems like low loss and crosstalk have been established in numerous long-haul system experiments. Recently more attention has been given to applications of space division multiplexing for short reach systems, including data center transmission and sensing applications. Short reach systems may be the first high volume application, as space division multiplexing for short reach systems has fewer remaining technical challenges. In addition to higher bandwidth density, space division multiplexed systems offer potential advantages in lower power consumption and cost. In this paper we present penalty-free bit error ratio results down to
