For several years, the two American optical companies Finisar and TE Connectivity have manufactured lasers side by side under the same roof in Järfälla.Then came the change.Last autumn, TE left the Swedish factory, while Finisar Sweden - which for a long time needed to expand - took over both the clean room and a large part of TE's staff.- When TE's premises became vacant, we saw the opportunity to expand into that part of the clean room.Right now we are moving in and in total this means that we will increase the area by roughly 50 percent, says Patrik Evaldsson, CEO of Finisar Sweden.Things are going well for Finisar Sweden.The facts speak for themselves.Even when I was in Järfälla two years ago and visited, the atmosphere was at its best.Then Patrik Evaldsson told us that the factory produced just over 100,000 lasers per year.Now that figure has more than doubled.- That is one reason why we now have the opportunity within the company to expand.Likewise, turnover has skyrocketed.Finisar Sweden's turnover was approximately SEK 235 million during the financial year that ended on April 1, 2016. This can be compared with SEK 103 million two years earlier.At the same time as manufacturing has increased, more people have also been hired, both on the engineering and production side.- Now we are about 125 people here in Järfälla.We have taken over a lot of staff from TE, so we have had the opportunity to hire very competent people, which has been good for both us and them, says Patrik Evaldsson.The MGY laser architecture, which is the cornerstone of the business, was originally developed within an EU project called Newton.The patent is owned by the research institute Imec, the University of Ghent and British Gayton Photonics, while Finisar has exclusive rights to the architecture.MGY stands for Modulated Grating Y-branch.The Y in the laser name comes from the appearance of the chip, where the two parallel legs each act as their own reflector.When the two reflectors are aligned to give reflection at the same wavelength, you get light at exactly that wavelength.Tunability comes from controlling the current through the two reflectors, as well as the part that joins the reflectors.With the technology, lasers can be created that cover the entire C-band – from 191.70 THz to 196.10 THz.A large part of Swedish competence is manufacturing laser components with a very high degree of integration.The key is to monolithically combine a so-called MGY laser (Modulated Grating Y-branch) that provides the tunability with an amplifier on an indium phosphide substrate.Some chips also integrate a modulator.Two years ago, the main volume of the laser chip went from the Swedish factory to the parent company's 10 Gbit system.The volume is still there, but the products that are now ramping up in Järfälla must be in the parent company's modules for systems that communicate with 100 Gbit/s or higher data rates.- In recent years, we have developed products for coherent communication, which is a requirement to reach 100Gbit/system or even higher, says Patrik Evaldsson, and he continues:- In coherent solutions, tunable lasers with very narrow linewidth and special modulators are needed.We have developed that technology and it is ramping up in production right now.It will ramp up a lot this year.Here he talks about lasers and modulators that can handle QAM modulation (quadrature amplitude modulation), mainly 16 QAM and 64 QAM.When asked what makes the Swedish business so successful, Patrik Evaldsson points to the American parent company.- Finisar is the market leader, so once the company produces a product, it goes in large volumes.Then you can invest.The fact that we are part of Finisar, and that pretty much everything we do here is used internally, is an important factor in our success.At the same time, the parent company lives in a market that is developing very well and customers that are willing to invest in new products.- The driving force is social media, which require more and more bandwidth, which means that the systems have to be expanded more and more, explains Patrik Evaldsson.Here, the Swedish operation - with experienced employees who have developed products, come up with new ideas and improvements - fits like a glove.A challenge that the engineers constantly face in Järfälla is to create lasers with a narrower line width.Likewise, an even higher degree of integration is essential.In today's solutions for coherent communication, the laser and modulator are divided into two units.In the long run, they must be integrated;a development project that is currently engaging the engineers in Järfälla.- In the end, it is cost and effect development that are most important when expanding the systems.Integration often leads to both lower costs and lower impact development.As more are integrated on the chip, they also get bigger.That is one reason why the company switched from 2- to 3-inch wafers in the factory.All new products are developed today on 3-in.We are also considering going to 4-inch.When we combine lasers, modulators, amplifiers and waveguides on the same chip, they become quite large.Then we need to go to larger and larger wafer sizes, says Patrik Evaldsson.Professor Jutta Haider leads a research project that will map how misinformation about sustainable electricity production arises online.Chinese FAW announces that it will use AI circuits from likewise Chinese Cambricon as brains in L2 driver assistance systems in future car models in the SEK 150,000 class.The choice illustrates how China faces the US export bans on advanced semiconductors.Democratic governance, stable bedrock, plenty of clean water and renewable electricity with low CO2 emissions plus a generally high level of technology make Sweden a perfect place for semiconductor manufacturing.Now it's just a matter of getting politicians and civil servants to realize it, write Elisabet Österlund and Peter Björkholm at the industry association Swedish Electronics in a debate article.The number of IoT nodes that are connected via satellite increases by roughly 40 percent per year to reach roughly 21 million in 2026.The figures come from the Gothenburg-based analysis house Berg Insight.Some of the 1,400 researchers at the world's largest solar cell lab at the German research institute Fraunhofer have found a new recipe for electroplating and spun off a company.They will go into pilot production early next year.New US export rules stop Nvidia and AMD from selling their latest supercomputer chips to China.Intel, Dell and Red Hat, there you have Telenor's lineup for the job of providing the 5G network with small clouds close to the users, often called the 5G Edge.The technology makes it easier for customers to develop new services with high security and short response times.The British IP giant Arm has sued the American Qualcomm for breach of contract.The dispute stems from Qualcomm's purchase of Nuvia and the subsequent dispute over what applies to the licenses the startup had with Arm.Nsitexe – a spin-off from automotive component supplier Denso – is developing an AI circuit for edge applications around a Risc V cpu.At the beginning of the year, Chinese Rigol launched two power units of the slightly more powerful kind.Now the company follows up with four simpler models.In the latest update of the Ericsson Mobility Report, the telecom giant states that the number of 5G subscribers increased by 70 million during the second quarter.There were thus 690 million around the world at the turn of the year.The American standards organization NIST has chosen the Falcon algorithm as the standard for post-quantum cryptographic digital signatures.The Falcon must withstand an attack with quantum computers.Seventeen names in the Risc V ecosystem have contributed kernels and tools to Pathfinder -
