“…For the high-speed output The coupling efficiency between the fiber ribbon and the photodiode array for the 12 channels was measured to be 78% f 5%. The overall crosstalk was measured using an analog version of the receiver (i.e., without the D-register chips) and was found to be less than -40 dB at clock frequencies Retimed synchronous output eye-diagrams of the data channels at up to 1 GHz [17]. The eye-diagrams of the data channels for a 622 Mb/s 27 -1 pseudo-random bit stream (PRBS) synchronous transmission are shown in Fig.…”

Given the high data rates (>500 Mb/s) achievable in optical links using current device technologies, low cost packaging of transmitters and receivers plays a key role in rendering them viable for short-haul data communication networks. The authors report a 12 channel, fully digital, hybrid receiver module for a synchronous parallel optical datalink operating at 622 MbMchannel. The use of a multichip module (MCM) and the passive alignment of the MT-connectorized multimode ribbon fiber to the photodetector array result in a simple low cost packaging solution.

ABSRACTA novel optical PCB with transmitter/receiver system boards and optical bakcplane was prepared, which is board-toboard interconnection by optical plug and slot. We report an 8Gb/s PRBS NRZ data transmission between transmitter system board and optical backplane embedded multimode polymeric waveguide arrays. The basic concept of ETRI's optical PCB is as follows; 1) Metal optical bench is integrated with optoelectronic devices, driver and receiver circuits, polymeric waveguide and access line PCB module. 2) Multimode polymeric waveguide inside an optical backplane, which is embedded into PCB. 3) Optical slot and plug for high-density(channel pitch : 500um) board-to-board interconnection. The polymeric waveguide technology can be used for transmission of data on transmitter/ receiver system boards and for backplane interconnections. The main components are low-loss tapered polymeric waveguides and a novel optical plug and slot for board-to-board interconnections, respectively. The optical PCB is characteristic of low coupling loss, easy insertion/extraction of the boards and, especially, reliable optical coupling unaffected from external environment after board insertion.

“…Several source-synchronous parallel optical interconnection designs in the application of multi-processors, chip-to-chip and board-toboard communication were reported in [42], [43], [44], [45], and [46], but the signaling schemes used in these systems were mainly based on SDR. In addition, the serialization and deserializaton digital circuits were located on a separate chip from the analog VCSEL driver and optical receiver circuits.…”

Public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing this collection of information. 12b. DISTRIBUTION CODE ABSTRACT (Maximum 200 Words)This project had two goals: To build an emulation prototype board for a tiled architecture and to demonstrate the utility of a global inter-chip free-space photonic interconnection fabric for polymorphous computer architectures (PCA). The free-space optics part of the project focused on two critical issues to validate the use of ultra-high-capacity global freespace interconnection fabrics for polymorphous computing architectures. These issues fell into the categories of interface issues and internal switch issues. The VCSEL-based free-space optical system was shown to be tolerant of misalignments, although electrical packaging problems prevented a full-performance demonstration. The optical links for the free-space system were demonstrated at 2.5 Gbps each with an inter-chip distance of about 10 cm. The project successfully demonstrated an optical inter-board fiber-based interconnect and intra-board free-space interconnect. The project also developed a prototype board that was demonstrated with an emulator of a tiled architecture.
