The making of integrated optics

A US initiative is bringing together leading companies with top academics and universities to create a manufacturing infrastructure for the widespread adoption of integrated photonics.

The US sees integrated photonics as a strategic technology and has set up the American Institute for Manufacturing Integrated Photonics - AIM Photonics - to advance the technology and make it available to a wider community of companies. AIM Photonics, with $610 million of public and private funding, is a five-year initiative ending in 2020. AIM’s long-term goal is to be self-sustaining.

“Right now the infrastructure is focussed on electronics and CMOS but photonics is going to be the future,” says Doug Coolbaugh, chief operations officer at AIM Photonics. “There is no other way to do it [very high bandwidth] except using light for ultra fast communications.”

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."
