Oops. I mean waveguide to fiber (not laser) coupling.

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.

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.

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 ?

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

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

NEXT UPCOMING BROADCAST
In conjunction with unveiling of EE Timesí Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
