ABSTRACT In this letter, we demonstrate error-free operation of a 12-fiber ×4-wavelength ×5.21-Gb/s parallel-wavelength-division-multiplexed (PWDM) optical link. The 250-Gb/s transmitter and receiver assemblies each have a 5×8-mm footprint and consume a combined power of 1.5 W. To our knowledge, this is the first publication of a fully functional PWDM optical interconnect as well as the highest demonstrated bandwidth per unit area and bandwidth per unit power consumption for any multiple-channel fiber-optic interconnect. This technology is intended for short-distance high-bandwidth-density applications such as multiprocessor computer backplanes.

    ABSTRACT: A tapered hollow waveguide multiplexer is proposed to combine the output of a multi-wavelength VCSEL array. The design of the proposed hollow waveguide is presented based on ray optics. We demonstrated the multiplexing of 4- channel output of a VCSEL array for coupling into a multi-mode fiber with the tapered hollow waveguide. The wavelength of each channel was allocated with adjusting driving current. The proposed hollow waveguide multiplexer is useful for realizing compact and low-cost WDM transceivers with a multi-wavelength VCSEL array for high capacity short reach optical networks.

    ABSTRACT: Optical interconnect architectures with electronic buffers have been proposed as a promising candidate for future high speed interconnections. Out of these architectures, the OpCut switch achieves low latency and minimizes optical-electronic-optical (O/E/O) conversions by allowing packets to cut-through the switch whenever possible. In an OpCut switch, a packet is converted and sent to the recirculating electronic buffers only if it cannot be directly routed to the switch output. In this paper, we study packet scheduling in the OpCut switch, aiming to achieve overall low packet latency while maintaining packet order. We first decompose the scheduling problem into three modules and present a basic scheduler with satisfactory performance. To relax the time constraint on computing a schedule and improve system throughput, we further propose a mechanism to pipeline packet scheduling in the OpCut switch by distributing the scheduling task to multiple “sub-schedulers.” An adaptive pipelining scheme is also proposed to minimize the extra delay introduced by pipelining. Our simulation results show that the OpCut switch with the proposed scheduling algorithms achieve close performance to the ideal output-queued (OQ) switch in terms of packet latency, and that the pipelined mechanism is effective in reducing scheduler complexity and improving throughput.
