Packaging silicon photonics using passive alignment  

  • An Israeli start-up is tackling a key packaging challenge for silicon photonics

Teramount has developed a way to simplify the packaging of silicon photonics chips. Instead of using active alignment whereby an external laser is required to carefully align a fibre to the optical die, the Israeli start-up has developed a technology that allows passive alignment.  

 

Hesham Taha“If we want silicon photonics to ramp up to volume, it has to meet CMOS standards both in terms of fabrication and packaging,” says Hesham Taha, Teramount's CEO.

Taha worked at a company developing atomic force microscopy systems before co-founding Teramount. "We got to know of the problem of injecting light into a waveguide and were surprised that the industry was still using active alignment," he says.

Professor Graham Reed: The calm before the storm

Silicon photonics luminaries series

Interview 3: Professor Graham Reed

Despite a half-century track record driving technology, electronics is increasingly calling upon optics for help. “It seems to me that this is a marriage that is really going to define the future,” says Graham Reed, professor of silicon photonics at the University of Southampton’s Optoelectronics Research Centre.

 

The optics alongside the electronics does not have to be silicon photonics, he says, but silicon as a photonics technology is attractive for several reasons. 

“What makes silicon photonics interesting is its promise to enable low-cost manufacturing, an important requirement for emerging consumer applications,” says Reed. And being silicon-based, it is much more compatible than other photonics technologies. “It probably means silicon photonics is going to win out,” he says.
