Interview: Finisar’s CEO reflects on a notable year

Michael Hurlston has had an eventful 2018. 

The year started with him replacing Finisar’s veteran CEO, Jerry Rawls, and it is now ending with Finisar being acquired by the firm II-VI for $3.2 billion.

Finisar is Hurlston’s first experience in the optical component industry, having spent his career in semiconductors. One year in and he already has strong views about the industry and its direction.

“We have seen in the semiconductor industry a period of massive consolidation in the last three to four years,” says Hurlston, in his first interview sinced the deal was announced. “I think it is not that different in optics: scales matters.”    

Hurlston says that, right from the start, he recognised the need to drive industry consolidation. “We had started thinking about that fairly deeply at the time the Lumentum-Oclaro acquisition was announced and that gave us more impetus to look at this,” says Hurlston. The result was revealed in November with the announced acquisition of Finisar by II-VI.

COBO: specification work nearing completion

The Consortium for On-board Optics (COBO) is on target to complete its specifications work by the year end. The work will then enter a final approval stage that will take up to a further three months.

On-board optics, also known as mid-board or embedded optics, have been available for years but vendors have so far had to use custom products. The goal of COBO, first announced in March 2015 and backed by such companies as Microsoft, Cisco Systems, Finisar and Intel, is to develop a technology roadmap and common specifications for on-board optics to ensure interoperability.

Brad Booth (pictured), the chair of COBO and principal architect for Microsoft’s Azure Global Networking Services, says that bringing optics inside systems raises a different set of issues compared to pluggable optical modules used on the front panel of equipment. “If you have a requirement for 32 ports on a faceplate, you know mechanically what you can build,” says Booth.

Interview 7: Professor John Bowers

August has been a notable month for John Bowers.

Juniper Networks announced its intention to acquire Aurrion, the US silicon photonics start-up that Bowers co-founded with Alexander Fang. And Intel, a company Bowers worked with on a hybrid integration laser-bonding technique, unveiled its first 100-gigabit silicon photonics transceivers.

Professor John BowersBower, a professor in the Department of Electrical and Computer Engineering at the University of California, Santa Barbara (UCSB), first started working in photonics in 1981 while at AT&T Bell Labs.

When he became interested in silicon photonics, it still lacked a good modulator and laser. "If you don't have a laser and a modulator, or a directly modulated laser, it is not a very interesting chip,” says Bowers. "So I started thinking how to do that."
