Mario Paniccia: We are just at the beginning

Silicon photonics luminaries series

Interview 2: Mario Paniccia

 

Talking about his time heading Intel’s silicon photonics development programme, Mario Paniccia, spotlights a particularly creative period between 2002 and 2008.  

 

During that time, his Intel team had six silicon photonics papers published in the science journals, Nature and Nature Photonics, and held several world records - for the fastest modulator, first at 1 gigabit, then 10 gigabit and finally 40 gigabit, the first pulsed and continuous-wave Raman silicon laser, the first hybrid silicon laser working with The University of California, Santa Barbara, and the fastest silicon germanium photo-detector operating at 40 gigabit.

 

“These [achievements] were all in one place, labs within 100 yards of each other; you had to pinch yourself sometimes,” he says.

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.

Monolithic silicon photonic chips move a step closer

Indium phosphide laser arrays have been grown on a 300 mm silicon wafer by Ghent University and imec, the Belgium nano-electronics R&D centre. Growing indium phosphide lasers directly onto the silicon wafer promises compact monolithic silicon photonics circuits.

Silicon photonics chips are hybrid designs because of silicon’s inability to generate light. Silicon photonics companies either couple a discrete laser to a chip or bond indium phosphide wafers or ‘chiplets' to the silicon wafer and process it to create working lasers that become part of the silicon photonics chip. Growing lasers directly on silicon creates a third approach for the densest applications.

Graphene prototype modulator shown working at 10 Gigabit

• Imec's graphene electro-absorption modulator works at 10 Gigabit-per-second
• The modulator is small and has be shown to be thermally stable
• Much work is required to develop the modulator commercially

Imec has demonstrated an optical modulator using graphene operating at up to 10 Gigabit. The Belgium nano-electronics centre is exploring graphene - carbon atoms linked in a 2D sheet - as part of its silicon photonics research programme investigating next-generation optical interconnect. Chinese vendor Huawei joined imec's programme late last year.

Huawei joins imec to research silicon photonics

Huawei has joined imec, the Belgium nano-electronics research centre, to develop optical interconnect using silicon photonics technology. The strategic agreement follows Huawei's 2013 acquisition of former imec silicon photonics spin-off, Caliopa.
