June 2017 edition – Vol.9 no.6

EDITORIAL

The 15th edition of the IEEE International NEWCAS Conference that was held from June 25 to 28 in Strasbourg, France, was organised by Professor Luc Hébrard’s team of the Université de Strasbourg joined by some members of ReSMiQ. Launched in 2003 in Montreal, under the sponsorship of the IEEE Circuits and Systems society (CAS), it has progressively grown to become a major meeting event and is now a full-fledged IEEE conference. This world-class conference has been hosted for the fifth time across the Atlantic in France after Grenoble (2015), Paris (2013), Bordeaux (2011) and Toulouse (2009). It is worth noting that the acceptance rate of 47.5% allowed the conference to achieve a remarkable level of quality. The spectrum of research topics covered this year attracted 191 submissions from over 30 countries. These were sorted and evaluated by the members of the technical committee and external reviewers who conducted in-depth evaluation of each paper. The final selection resulted in the presentation of 73 articles in lecture sessions and 29 in poster sessions. It was also a great honor to welcome world renowned speakers who shared their knowledge and their expertise with the attendees such as Edoardo Charbon, of the École polytechnique fédérale de Lausanne, Nando Basile, of X-FAB and co-founder of Spike 3D Concept engineering, and Pantelis Georgiou, of the Imperial College in London. We congratulate all the members of the organizing committee for this success and we also take this opportunity to thank the sponsors for their support. It is in this spirit that we look forward to seeing you next year in Montréal from June 24 to 27 of 2018.

We are pleased to announce that ReSMiQ has a new member, professor Paul-Vahé Cicek of the department of computer science at Université du Québec à Montréal. He works in the field of convergent integration of microtechnologies.


ReSMiQ is a group of researchers in an interuniversity research center that can count on the support of the Fonds de recherche du Québec – Nature et technologies (FRQNT) and nine (9) Quebec universities involved in microsystems research.

RESEARCH CONTRIBUTIONS

A Source-Synchronous Architecture Using Mode-Division
Multiplexing for On-Chip Silicon Photonic Interconnects

A source-synchronous interconnect using mode-division multiplexing (MDM) for potential use in on-chip applications is experimentally demonstrated using a 3-mode 750 μm Silicon photonics structure. Results are presented for simultaneous transmission of two data channels on two separate modes (bit error rate <; 10-12 at 10 Gb/s) sampled by an optically forwarded clock sent on a third separate mode. Performance assessment of the mode assignment for the clock is presented. The investigation shows that an optimum clock placement is important at wavelengths where modal crosstalk is higher. For example, at 1553 nm, the clock's jitter decreases from 45 ps down to 2.7 ps where the clock is encoded on a mode with high crosstalk (-18.6 dB) to one that has less crosstalk (-28.6 dB). At 1560 nm where modal crosstalk is better, the clock's jitter is 2.6 ps (-27.8 dB crosstalk) and 1.1 ps (-34 dB crosstalk) without and with optimum clock placement, respectively. With proper clock to mode assignment, the optical interconnect becomes functional across an optical bandwidth of 11 nm enabling MDM-wavelength-division multiplexing architectures.

Fig. 1. Proposed MDM architecture. The transmit side (TX) modulates data on single-mode waveguides (SM WG), which are multiplexed onto different modes (1 to N), along with the transmit clock on a separate mode (Mode 1 in this illustration). On the receive side (RX), the optical signals are optically mode-demultiplexed onto SM WG, and then electrically recovered using the forwarded clock which is deskewed (phase aligned) and used in the latches.

Fig. 3. Electrical eye diagrams of data transmission at 1553 nm captured with oscilloscope triggered by the forwarded (a) optical clock on mode 2 and (b) electrical clock bypassing the DUT. As observed, the method of sending the clock notably changes the eye. Closure of the eye horizontally is caused by modal crosstalk induced jitter.
