Rockley Photonics eyes multiple markets

Andrew Rickman, founder and CEO of silicon photonics start-up, Rockley Photonics, discusses the new joint venture with Hengtong Optic-Electric, the benefits of the company’s micron-wide optical waveguides and why the timing is right for silicon photonics. 

Andrew Rickman

The joint venture between Rockley Photonics and Chinese firm Hengtong Optic-Electric is the first announced example of Rockley’s business branching out.

The start-up’s focus has been to apply its silicon photonics know-how to data-centre applications. In particular, Rockley has developed an Opto-ASIC package that combines optical transceiver technology with its own switch chip design. Now it is using the transceiver technology for its joint venture.

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."

Imec gears up for the Internet of Things economy  

Luc Van den hove is talking in the darkened ballroom in a hotel next to the brilliantly sunlit marina in Herzliya.

It is the imec's CEO's first trip to Israel and around us the room is being prepared for an afternoon of presentations the Belgium nanoelectronics research centre will give on its work in such areas as the Internet of Things and 5G wireless to an audience of Israeli start-ups and entrepreneurs.


Luc Van den hoveImec announced in February its plan to merge with iMinds, a Belgium research centre specialising in systems software and security, a move that will add 1,000 staff to imec's 2,500 researchers.

At first glance, the world-renown semiconductor process technology R&D centre joining forces with a systems house is a surprising move. But for Van den hove, it is a natural development as the company continues to grow from its technology origins to include systems-based research.
