  • Silicon Photonics Report
    Silicon Photonics Report March 2020 Scope of the Report This report looks at Silicon Photonics from a communication and datacom perspective. It is becoming clear that the attributes that make Silicon Photonics compelling for communication/datacom also apply to the sensor market. We will look at the sensor market in a separate report, but our understanding of the market, verified by our visit to Photonics West, is that the sensor market offers a larger market opportunity than datacom for Silicon Photonics. Examples that steer our opinions: 1. Brolis Semiconductor – showing a very compelling medically focused spectrometer that is based on a silicon integrated circuit which is clearly applicable to not only the professional medical market, but also the consumer medical market 2. Other companies such as Rockley Photonics have used their platform technology to demonstrate numerous sensor applications compatible with markets that would demand hundreds of millions of units per annum. Much like their announcements around the commercialisation of their LightDriver™ products it would surprise us if there were not similar announcements focused on the sensor application products they have been developing Silicon Photonics Report – March 2020 Page | 2 RCL Background Mike Powell is the Managing Director and Partner of Renevo Capital Limited. Mike focuses on the TMT and Advanced Materials sectors. He has 15 years experience advising companies internationally on M&A, financing, and corporate strategy. He is extremely well connected across Europe, the North Americas and China.

  • System Interconnect Fabrics: Ethernet Versus Rapidio® Technology
    Technology White Paper System Interconnect Fabrics: Ethernet versus RapidIO® Technology By Greg Shippen, System Architect Freescale Semiconductor’s Digital Systems Division, NCSG Member, RapidIO Trade Association Technical Working Group and Steering Committee RapidIO® Trade Association - 3925 W. Braker Lane, Ste. 325 - Austin, Texas 78759 - 512.305.0070 Used by permission. Foreword An important trend in the embedded industry is the move from proprietary solutions toward standard interconnects and mechanicals (e.g. ATCA, Ethernet, RapidIO®). Traditionally, Ethernet is the incumbent interconnect technology for embedded systems, yet the existence of alternatives has been driven by the realization that some high-performance applications exceed the limits of this traditional protocol. The RapidIO standard, with growing switch, DSP and processor endpoint support, has been deployed in many applications and continues to gain widespread support. RapidIO is particularly popular in wireless infrastructure equipment, where DSP connectivity is critical. As Ethernet and RapidIO continue to evolve, a comprehensive review and comparison is needed to help designers evaluate and select the protocol that best suits their next-generation designs. This white paper, System Interconnect Fabrics: Ethernet Versus RapidIO Technology, is a comprehensive compilation of embedded interconnect information. It provides a high- level market perspective and delivers a detailed technical examination of these two technologies. The paper begins with a top-level description of market requirements for the logical, transport, and physical layers, then moves into a thorough discussion of each protocol. The author builds a foundation for comparison and discussion through an historical overview of both RapidIO and Ethernet. Understanding the origin of these two standards helps to clarify their current use in embedded applications.

    100Gb/s Single Lambda Optics – Why ? Gary Nicholl, Principal Engineer, TMG Cisco OIDA 100GbE per Lambda for Data Center Workshop – June 12-13 2014 1 . Traffic growth continues at all levels . System implementation requires innovation on many technology fronts: - Optics, ASIC, Power, Thermals, PCB, Serdes, Memory, Packaging, …… . Optical technology is becoming one of the key challenges for many system implementers: - size, power and cost All optical technologies have matured (are maturing) over time to the lowest size, cost, power 100M1G10G40G(100G?) 2 . 100Gb/s Ethernet is in transition. For the past 4 years 100GbE has been primarily deployed as a core networking technology - A first for Ethernet - Port density/cost not the overriding factor - Well served by 100G-LR4 optics . 100Gb/s Ethernet is just starting to move into the data center switching space - Enabled by upcoming availability of high 100Gb/s port count merchant switching silicon - Port density/cost is now everything - Puts increased pressure on size, power, cost of 100Gb/s optics - Recent activities on 100G CWDM a response to this 3 . The cost of an optical module is dominated by cost of optical components and associated packaging. Reducing the optical lane width, reduces nowell_01_0911_NG100GOPTX the number of optical components and hence the cost . A single lambda solution is the solution with the lowest optical component count, and has historically resulted in the lowest cost nicholl_01_0112_NG100GOPTX . The discussion is not if 100Gb/s single lambda is compelling but when: . When is it technically feasible ? . How hard should we push to make it feasible ? . Do we need to do anything else in the interim ? 4 10 Gigabit Ethernet Initial industry focus was on 10GBase-LX4 (4x3.125G CWDM) Starting point Leverage 2.5G optics, 10G was too challenging/costly Industry conclusion packaging complexity kills CWDM vs.

Growing need for 500m~2km / SMF intra-DC connections. Interest in breakout / fanout capabilities Ethernet WAN / Transport Interconnect. 2km, 10km, 40km – continued need. SMF 100GE. 2nd generation of devices becoming available. Smaller size, lower cost, lower power. 400GE project started. Intra-DC, Inter-DC, and Metro reach objectives. New class of coherent tunable pluggable T/Rs. Metro reach & compatible with ROADMs Optical reach over ROADM still TBD.

Recent discussion: 100GE 4-lane module (4 x 25G VCSEL): • 4 x 25GE - An IEEE 802.3 25GE Study Group is underway.
