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.

Users embrace OpenLight's silicon photonics platform

OpenLight, the open silicon photonics platform provider, can point to a successful 2024 signing up new customers. 

In 2023, OpenLight had three customers bringing photonic integrated circuit (PIC) designs to market. OpenLight has since added 14 more.  

OpenLight was formed in 2022 when Juniper Networks carved out its silicon photonics arm. Synopsys acquired a three-quarters stake in OpenLight, while Juniper retained a quarter.

“In the past, the company hadn’t really done any revenue, including when they were in Juniper,” says Adam Carter, OpenLight’s CEO (pictured). “We’ve seen a ten times increase and shown that we can be very profitable.”

The start-up has been creating industry partnerships to better serve its customers' circuit design, chip manufacturing, and packaging needs.

OpenLight's CEO on its silicon photonics strategy

Adam Carter, recently appointed the CEO of OpenLight, discusses the company’s strategy and the market opportunities for silicon photonics.

Adam Carter, CEO of OpenLight

Adam Carter’s path to becoming OpenLight’s first CEO is a circuitous one.

OpenLight, a start-up, offers the marketplace an open silicon photonics platform with integrated lasers and gain blocks.

Having worked at Cisco and Oclaro, which was acquired by Lumentum in 2018, Carter decided to take six months off. Covid then hit, prolonging his time out.

Carter returned as a consultant working with firms, including a venture capitalist (VC). The VC alerted him about OpenLight’s search for a CEO.

Carter’s interest in OpenLight was immediate. He already knew the technology and OpenLight’s engineering team and recognised the platform’s market potential.

“If it works in the way I think it can work, it [the platform] could be very interesting for many companies who don't have access to the [silicon photonics] technology,” says Carter.

Lumentum’s CTO discusses photonic trends

CTO interviews part 2: Brandon Collings

• The importance of moving to parallel channels will only increase given the continual growth in bandwidth.
• Lumentum's integration of NeoPhotonics’ engineers and products has been completed.
• The use of coherent techniques continues to grow, which is why Lumentum acquired the telecom transmission product lines and staff of IPG Photonics.

Brandon Collings has been a CTO for over 13 years; first as CTO of the commercial optical products (CCOP) business within JDSU and then CTO of Lumentum when it spun out in 2015. In that time, the scope of his work has continued to grow.

"It has changed quite significantly given what Lumentum is engaging in," he says. "My role spans the entire company; I'm engaged in a lot of areas well beyond communications."

A decade ago, the main focus was telecom and datacom. Now Lumentum also addresses commercial lasers, 3D sensing, and, increasingly, automotive lidar.

OpenLight's integrated-laser silicon photonics platform

• OpenLight is an independent silicon photonics company backed by Synopsys and Juniper Networks 
• The company was created by carving out the silicon photonics arm of Juniper
• The establishment of OpenLight and its open platform highlights the growing maturity of silicon photonics as new applications emerge beyond datacom and telecom

Thomas Mader, OpenLight

OpenLight is coming to market with an open silicon photonics platform that includes integrated lasers and gain blocks.

Juniper has a long relationship with Synopsys, using its electronic-photonic design automation (EPDA) tools.

So when Juniper said it was spinning out its silicon photonics group, Synopsys was keen to partner.

The result is OpenLight, of which Synopsys has a 75 per cent stake costing $67.5 million.

Thomas Mader, OpenLight's chief operating officer and formerly head of Juniper's silicon photonics unit, says OpenLight is the first company to offer an open platform that includes monolithically integrated lasers, optical amplifiers and modulators.

Intel details its 800-gigabit DR8 optical module

The company earmarks 2023 for its first co-packaged optics product

Intel is sampling an 800-gigabit DR8 in an OSFP pluggable optical module, as announced at the recent OFC virtual conference and show.

Robert Blum“It is the first time we have done a pluggable module with 100-gigabit electrical serdes [serialisers/ deserialisers],” says Robert Blum, Intel’s senior director, marketing and new business. “The transition for the industry to 100-gigabit serdes is a big step.”

The 800-gigabit DR8 module has eight electrical 100-gigabit interfaces and eight single-mode 100-gigabit optical channels in each transmission direction.

The attraction of the single-module DR8 design, says Blum, is that it effectively comprises two 400-gigabit DR4 modules. “The optical interface allows you the flexibility that you can break it out into 400-gigabit DR4,” says Blum. “You can also do single 100-gigabit breakouts or you can do 800-gigabit-to-800-gigabit traffic.”

400-gigabit coherent modules finally hit their stride

NeoPhotonics discusses 400-gigabit coherent modules, the move to 130-gigabaud symbol-rate optical components and a company tunable laser milestone.

NeoPhotonics’ 400ZR pluggable optical modules are now available and will ship in volume from the autumn.

“The QSFP-DD and OSFP 400ZR [optical modules] have passed qualification tests and we are engaged in numerous customer qualifications around the world,” says Ferris Lipscomb, vice president of marketing at NeoPhotonics.

400ZR modules implement the OIF’s 400-gigabit standard to connect directly equipment in data centres up to 120km apart without needing separate dedicated dense wavelength-division multiplexing (DWDM) optical transport equipment. The first 400ZR modules will be used by data centre operators.

But coherent pluggables support longer-reach modes. These may be interoperable if implementing the OpenZR+ multi-source agreement (MSA) or when delivering custom optical performance that are referred to as ZR+ modules.

NeoPhotonics has reported that its 400-gigabit coherent QSFP-DD when operated as a ZR+ module can achieve an 800km reach.
