Startup builds 100-Gbps laser in CMOS

LONDON – Skorpios Technologies Inc., a 2009 startup developing silicon photonics and backed by numerous telecoms companies, has demonstrated a C-Band tunable photonic laser manufactured using a proprietary process.
The Skorpios' STAB process delivers wafer-scale, single-chip integration of optoelectronic devices and CMOS, thereby permitting extremely low-cost and scalable solutions, the company said.
The laser was made using the Skorpios STAB process at commercial foundry. The result is photonic CMOS IC that is planar and hermetically encapsulated. Additionally, the Skorpios CMOS laser IC does not require post-fabrication assembly processes such as flip-chip bonding, turning mirrors, lenses or active alignments.
Early characterization of the initial devices indicates they are suitable for datacenter interconnects and for coherent long-haul systems at data rates of 100-Gbits per second, the company said. The benefits include narrow linewidth, high side-mode suppression, a wide range of tunability and no requirement for active cooling or hermetic packaging.
Products based on Skorpios' STAB platform offer an order of magnitude cost reduction compared with previous, equivalent performance lasers, Skorpios said. The laser means that for the first time wavelength-division multiplex (WDM) can be deployed within the data center and it will also reduce the cost of implementing long-haul and metro communication networks, said Stephen Krasulick, founder and CEO of Skorpios Technologies (Albuquerque, New Mexico), in a statement.
Jan Haeglund, Ericsson's head of IP broadband networks, said that Skorpios delivering the first tunable laser based on the STAB process removes the last barriers to achieving a CMOS ASIC-like business model for optics. "We are a step closer to delivering next generation IP networks that are even lower cost and more scalable than today's. Ericsson's 4G IP portfolio will benefit from this pioneering technology in the coming years," he said, in a statement issued by Skorpios.
"This opens a clear path for high photonic integration in a low cost material system fitting ideally to new metro access applications," said Antonio Teixeira, senior specialist at Nokia Siemens Networks.
Ericsson, Nokia Siemens Networks and Deutsche Telekom are investors in Skorpios.

Laser in CMOS!...this will be huge if it works as advertised!!...we would love to have this technology presented at CMOS Emerging Technologies symposium in Whistler this JUly (www.cmosetr.com), if anyone at Skorpios is interested pls contact me, kris.iniewski@gmail.com

Strictly, CMOS should not imply Silicon. You can have III-V CMOS.

How about the reliability ? Luxtera bonds laser chip on CMOS wafer, what's the difference ? Only laser is not enough, has Skorpios developed receiver, modulator...with high perfomance ? Infinera has realized WDM on chip on III-V platform, will Skorpios's solution be cheaper and better ?

If you put four 25Gbps lasers on a chip, are you allowed to call this a 100Gbps laser?
There would appear to be a wide gap between the press release title and what may have been actually demonstrated.
Some have other names for such a gap, 'factor of 4 or 10' comes to mind.

I guess it's another example of hybrid "Si" laser with III-V and Si wafer bonding technology pioneered by UCSB/intel and some European teams. In another report, they claim they still have some problems with waveguide to laser coupling which is critical for any practical uses. I guess they can't use grating coupler as Luxteta has protected this little trick with a bunch of patents. Anyway, we will see how it looks like in the upcoming OFC.
@laser_jock, it refers to 100G because of the IEEE 100GbE LR4 (4x25G) standard.
