By invitation: Professor Roel Baets on Silicon Photonics 4.0

Roel Baets, Emeritus Professor at Ghent University and former Group Leader at imec gave a plenary talk on 'Silicon Photonics 4.0' at the recent ECOC conference. "It will be important for silicon photonics to make use of smart and agile manufacturing, a notion associated with Industry 4.0," said Professor Baets, explaining the title.

In a guest piece, he explains his thoughts and discusses what he saw at ECOC. He also has a request.

One of the things I discussed in my ECOC plenary talk was the large gap between research and product development for new applications of photonic integrated circuits (PICs) on the one hand, and product sales and new industrial process flows on the other.

Among many reasons for this gap, one stands out: the major barriers that fabless start-ups face when developing a product based on a still immature industrial supply chain.

The markets for photonic integrated circuits in 2030

What will be the leading markets for photonic integrated circuits (PICs) by the decade's end? And what are the challenges facing the PIC industry?

A panel session at the recent PIC Summit Europe event held in Eindhoven, The Netherlands, looked at what would be the markets for photonic integrated circuits by 2030.

The market for PICs is dominated by datacom and telecom. However, emerging applications include medical and wearable devices, optical computing, autonomous vehicles, and sensing applications for the oil, gas, water, and agriculture industries.

ECOC 2024 industry reflections - Final Part

In the final part, industry figures share their thoughts after attending the recent 50th-anniversary ECOC show in Frankfurt. Contributions are from Adtran’s Jörg-Peter Elbers, Lightwave Logic’s Michael Lebby, and Heavy Reading’s Sterling Perrin.

ECOC celebrated its 50th anniversary this year. It was great to see scientists, engineers, and industry leaders from all around the globe at a vibrant gathering in Frankfurt.

ECOC dates to September 1975 when the inaugural event – dubbed the “European Conference on Optical Fiber Technology” - was held in London. In the early days, the focus was on megabit-per-second transmission for telephony applications. Now, we are advancing to petabit-per-second speeds to meet AI and cloud services demands.

ECOC 2024 industry reflections - Part III

Gazettabyte is asking industry figures for their thoughts after attending the recent 50th-anniversary ECOC show in Frankfurt. Here are contributions from Aloe Semiconductor's Chris Doerr, Hacene Chaouch of Arista Networks, and Lumentum's Marc Stiller.

If there was one overall message from ECOC 2024 this year, it is that incumbent technologies are winning in the communications market.

Copper is not giving up. It consumes less power and is cheaper than optics, and now, more electronics such as retimers are being applied to keep direct-attach copper (DAC) cables going.  Also, 200-plus gigabaud (GBd) made a debut in coherent optics, but in intensity-modulation direct-detect (IMDD), 50GBd and 100GBd look like they are here to stay for several more years.

Is 6G’s fate to repeat the failings of 5G wireless?

Will the telecom industry embark on another costly wireless upgrade? Telecom consultant and author William Webb thinks so and warns that it risks repeating what happened with 5G.

William Webb published the book The 5G Myth in 2016. In it, he warned that the then-emerging 5G standard would prove costly and fail to deliver on the bold promises made for the emerging wireless technology.

Webb sees history repeating itself with 6G, the next wireless standard generation. In his latest book, The 6G Manifesto, he reflects on the emerging standard and outlines what the industry and its most significant stakeholder - the telecom operators - could do instead.

Developing a new generation wireless standard every decade has proved beneficial, says Webb. However, the underlying benefits with each generation has diminished to the degree that, with 5G, it is questionable whether the latest generation was needed.

First 50G-PON merchant silicon spurs operator trials

Broadcom has unveiled the industry’s first merchant silicon for the 50-gigabit passive optical network (50G-PON) access standard. Until now, only access equipment players such as Huawei and ZTE had their own 50G-PON silicon.

Broadcom has announced two 50G-PON devices: an optical line terminal (OLT) chip and the optical networking unit (ONU) 50-PON port to the users.  Both chips include custom hardware from Broadcom to run artificial intelligence (AI) machine-learning algorithms. 

Jim Muth, senior manager of product marketing at Broadcom, says supporting AI benefits the operator and the quality of the end user’s broadband service.

ECOC 2024 industry reflections - Part II

Gazettabyte is asking industry figures for their thoughts after attending the recent 50th-anniversary ECOC show in Frankfurt. Here are contributions from Nubis Communications' Dan Harding, imec's Peter Ossieur, and Chris Cole.

Our biggest takeaway from ECOC is the increased confidence not just in 200-gigabit electrical and optical interfaces but also in 400 gigabit. It is becoming clear that in 2025 and 2026, the industry will broadly launch platforms using a 200 gigabit per lane serdes [serialiser/deserialiser interfaces] that will connect to 200 gigabit per lane optics.
