17:00	4.1.1	ENERGY-PERFORMANCE OPTIMIZED DESIGN OF SILICON PHOTONIC INTERCONNECTION NETWORKS FOR HIGH-PERFORMANCE COMPUTING Speaker: Keren Bergman, Columbia University, US Authors: Meisam Bahadori¹, Sebastien Rumley¹, Robert Polster¹, Alexander Gazman¹, Matt Traverso², Mark Webster², Kaushik Patel² and Keren Bergman¹ ¹Columbia University, US; ²Cisco System, US Abstract We present detailed electrical and optical models of the elements that comprise a WDM silicon photonic link. The electronics is assumed to be based on 65 nm CMOS node and the optical modulators and demultiplexers are based on microring resonators. The goal of this study is to analyze the energy consumption and scalability of the link by finding the right combination of (number of channels X data rate per channel) that fully covers the available optical power budget. Based on the set of empirical and analytical models presented in this work, a maximum capacity of 0.75 Tbps can be envisioned for a point-topoint link with an energy consumption of 1.9 pJ/bit. Sub-pJ/bit energy consumption is also predicted for aggregated bitrates up to 0.35 Tbps. Download Paper (PDF; Only available from the DATE venue WiFi)
17:30	4.1.2	RAPID GROWTH OF IP TRAFFIC IS DRIVING ADOPTION OF SILICON PHOTONICS IN DATA CENTERS Speaker and Author: Kaushik Patel, Cisco Systems, US Abstract With the dramatic growth in consumers using Mobile plus Video data and the corresponding increase in IP traffic, more Data Centers are required together with a need to scale the capacity within the Data Centers. Moore's law continues to push advances in CMOS technology enabling the design of larger higher capacity ASICs used to build Switches and Routers in the Data Centers. The cost, power dissipation and face plate optical density challenges are being solved by Silicon Photonics deployed in smaller form factor pluggable optics with a longer term transition to embedded optics. This march towards higher data rates, lower cost and lower power dissipation requires major advances in the cost, volume wafer manufacturing, optical packaging and test for Silicon Photonics based products. The focus of this talk will be on how Cisco is addressing these multiple development and manufacturing challenges as Silicon Photonics based products are released in the market.

We demonstrate that integrated quantum frequency combs (based on high-Q microring resonators made from a CMOS- compatible, high refractive-index glass platform) can enable, among others, the generation of heralded single photons, cross-polarized photon pairs, as well as bi- and multi-photon entangled qubit states over a broad frequency comb covering the S, C, L telecommunications band, constituting an important cornerstone for future practical implementations of photonic quantum information processing.
