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.

Dan Harding, CEO, Nubis Communications

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.

A coherent roadmap for co-packaged optics

Is coherent optics how co-packaged will continue to scale? Pilot Photonics certainly thinks so.

Part 1: Co-packaged optics 

Frank Smyth

Frank Smyth, CTO and founder of Pilot Photonics, believes the firm is at an important inflection point. 

Known for its comb laser technology, Pilot Photonics has just been awarded a €2.5 million European Innovation Council grant to develop its light-source technology for co-packaged optics. 

The Irish start-up is also moving to much larger premises and is on a recruitment drive. “Many of our projects and technologies are maturing,” says Smyth.

Nubis' bandwidth-packed tiny optical engine

• Nubis Communications has revealed its ambitions to be an optical input-output (I/O) solutions provider
• Its tiny 1.6-terabit optical engine measures 5mm x 7.5mm
• The optical engine has a power consumption of below 4 picojoule/bit (pJ/b) and a bandwidth density of 0.5 terabits per millimetre.
• “Future systems will be I/O with an ASIC dangling off it.”

Nubis Communications has ended its period of secrecy to unveil an optical engine targeted at systems with demanding data input-output requirements.

Dan HardingThe start-up claims its optical engine delivers unmatched bandwidth density measured in terabits per millimetre (T/mm) and power consumption performance metrics.

“In the timeframe of founding the company [in 2020], it became obvious that the solution space [for our product] was machine learning-artificial intelligence,” says Dan Harding, the CEO of Nubis.
