ST makes its first PSM4 optical engine deliveries

Flavio Benetti is upbeat about the prospects of silicon photonics. “Silicon photonics as a market is at a turning point this year,” he says.

What gives Benetti confidence is the demand he is seeing for 100-gigabit transceivers in the data centre. “From my visibility today, the tipping point is 2016,” says Benetti, group vice president and general manager, digital and mixed processes ASIC division at STMicroelectronics.

Benetti and colleagues at ST have spent the last four years working to bring to market the silicon photonics technology that the chip company licensed from Luxtera.

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.

First silicon photonics devices from STMicro in 2014

STMicroelectronics expects to have first silicon photonics products by mid-2014. The chip company announced the licensing of silicon photonics technology from Luxtera in March 2012. Since then STMicro has been developing its 300mm (12-inch) CMOS wafer manufacturing line for silicon photonics at its fab at Crolles, France.

"We think we are the only ones doing the processing in a 12-inch line," says Flavio Benetti, general manager of  mixed processes division at STMicroelectronics.
