23 Mar 2016

As the giant optical comms expo, OFC, wraps up in Anaheim, CA, optics.org reviews some of the new

silicon photonics developments.

This week, OFC, the largest global

conference and exhibition for optical

communications and networking

professionals, now 40 years old, has

taken over the convention center in

Anaheim, California. The setting is

just a few hops from Disneyland,

which itself turned 60 last year. As

ever, OFC has drawn thousands of

attendees from all corners of the

globe to discuss and learn about the

latest in optical communications.

In 2016, it seems, many silicon

photonics developments and real

products have been making their

debuts at the show. So optics.org has

taken a closer look at some of these

launches; silicon photonics is

considered by many industry analysts

to be a disruptive technologyinwaiting.

Kaiam shows 100G CWDM4 SiP transceiver

Kaiam, a developer of hybrid photonic integrated circuit technology, is demonstrating what it is calling “the

world’s first” 100Gb/s CWDM4 silicon photonics transceiver. To showcase the capability of the transceiver, Kaiam

conducted a live demonstration, in which the module is connected to a standard directlymodulated laser version

of the company’s own CWDM4 transceivers through 10km of single mode fiber.

Dr. Ron Kaneshiro, VP Engineering at Kaiam, said, “Data center

operators are continually looking for performance and cost improvements

as many of them transition to WDM interfaces. This silicon photonics

transceiver highlights that Kaiam has the tools available to deliver

products in volume to meet and exceed our customers’ demands."

IRT Nanoelec puts laser on silicon with MZmodulator

IRT Nanoelec, an R&D consortium focused on information and

communication technologies using micro and nanoelectronics,

presented the integration of a IIIV/silicon laser and silicon Mach Zehnder

modulator, achieving 25 Gbps transmission on a single channel.

Integrating photonics capabilities on silicon chips is replacing currently

established technologies, vastly increasing bandwidth, density and

reliability, while dramatically reducing energy consumption. In the age of

photonicsonsilicon, data transmission will be measured in terabits/s.

Stéphane Bernabé, project manager, said, “These results were jointly

obtained by STMicroelectronics and Leti in the frame of the IRT

Nanoelec cooperation. Fabricating the laser directly on silicon

demonstrates IRT Nanoelec’s capability in III/Vonsilicon integration to

achieve such highdatarate fiberoptic module. IRT Nanoelec and its

partners on this project, Leti, STMicroelectronics, Samtec and Mentor

Graphics, are paving the way to integrating this technology in next

generation transceivers for optical data links.”

200Gb/s InfiniBand and Ethernet interconnect infrastructure."Silicon photonics is the enabling technology for 200Gb/s InfiniBand and Ethernet networks," said Amir Prescher, executive

vice president of business development and interconnect products at Mellanox. "The QSFP56 doubles the front panel

density for next generation switches; enables 200G copper DACs and 50G breakout cables for adapters and insidetherack

applications; and silicon photonics transceivers supports all data center reaches to 2km."

Mellanox plans to offer 50Gb/s and 200Gb/s Direct Attach Copper cables (DACs); copper splitter cables (QSFP56 to 4x

SFP56); silicon photonics based AOCs for reaches to 200m; and silicon photonics transceivers for reaches to 2km.

Mellanox 200Gb/s cables and transceivers will seamlessly support previous generations of 40 and 100Gb/s networks.

"The transition from 40G to 100G networks inside the data center has begun in earnest," said Dale Murray, principal

analyst at LightCounting Market Research. "This announcement comes just as the cloud and hyperscalers are planning

their migration to 200G and 400G."Mellanox's extensive LinkX interconnect product family includes 10, 40, 25, 50 and 100Gb/s copper cables, active optical

cables and transceivers for both single mode fiber and multimode fiber applications. The newest LinkX additions,

introduced at OFC 2016, are 25Gb/s transceivers and Active Optical cables, and use the SFP28 form factor.

The demo will take place for the first time at OFC 2016, OFC, March 2224, Anaheim, CA at the Mellanox booth, No. 3425.

UPDATE - Luxtera Ships One Millionth Silicon Photonic

Transceiver Product

Global Market Leader Crosses 1M Milestone as ECOC 2016 Kicks Off

DUSSELDORF, GERMANY and CARLSBAD, CA--(Marketwired - Sep 19, 2016) - ECOC 2016

-- Luxtera, Inc., the global leader in silicon photonics, today announced that the company has

shipped more than one million Silicon Photonic Parallel Single Mode fiber 4-lane (PSM4)

transceiver products. Its patented technology blends long reach capabilit ies of single mode

fiber with low cost transceivers. This combination is critical for the cost effective scaling of

cloud computing data centers.

" This is a huge milestone for the optics industry and an exciting achievement for Luxtera,"

said Greg Young, President and CEO of Luxtera. " With over 1 million units deployed,

sweeping design wins, and 100Gbps PSM4 shipping in 100K+ volumes, it is clear that our

products are at the center of the industry's $5 billion optical super cycle. Passing this

milestone signals that our customers have embraced our vision, including volume orders for

solutions that offer long reach and low cost with best in class performance."

A critical component of driving cost effective optics inside the data center was the

introduction of Parallel Single Mode (PSM) fiber optic solutions. Luxtera was the first to

recognize this application and has led the standardization efforts to allow multivendor

interoperability of PSM4. Luxtera was a founding member and drafter of the 100G-PSM4

Multi Supplier Agreement (MSA) in 2014, the first standard to enable silicon photonics

interoperability with legacy DML Optical modules for PSM4 fiber without compromising the

cost benefits of silicon photonics. This widely accepted MSA has the support of dozens of

companies with PSM4 product offerings and is being deployed at scale by the major cloud

computing operators. Luxtera has continued to drive further adoption of PSM4 for higher

data rates, and has been standardized in IEEE 802.3bs, 200GBase-DR4 and 400GBase-DR4

specifications, creating a seamless migration path to 400G.

Each Luxtera 100G PSM4 optical transceiver product includes four independently operating

transmitter and receiver channels, integrating high-speed phase modulators, photodetectors,

waveguides, grating couplers, high-speed electrical retimers, and integrated control circuitry,

powered by a single integrated laser. These components combine into a fully integrated

silicon photonics chipset or PSM4 optical engine with no additional external elements

required. Luxtera has now shipped over 1 million PSM4 transceiver products and has a broad

and growing customer base including major cloud datacenter operators, system OEMs, HPC

operators, and many additional users.

As part of a global tour to mark the 1M achievement, Luxtera's Vice President of Engineering

Peter De Dobbelaere, PhD, will be presenting on datacenter photonics at the 4th Optical
