Rick, this was a very interesting read, still looks like the race is on now and our polymer photonics entry may just be poised to take the lead, the below referenced excerpt seems to say VCSELS are at the front now but soon will be at the back of the race, do you think that POET will have great success near-term with their VCSEL/AOC any then lose ground later? excerpt from the article:

Yet Bowers is also pragmatic. “It still takes time,” he says. “You can demonstrate an idea, but it takes time to make it viable commercially.”

He points to the recently announced switch from Oracle that uses mid-board optics. “That is a commercial product out there now,” he says. “But is it silicon photonics? No, it is VCSEL-based; that is the battle going on now.”

VCSELs have won the initial battle in the data centre but the amount of integration the technology can support is limited. Once designers move to wavelength-division multiplexing to get to higher capacities, where planar technology is required to combine and separate the different wavelengths efficiently, that is when silicon has an advantage, he says.

The battle at 100 gigabit between VCSELs and silicon photonics is also one that Bowers believes silicon photonics will eventually win. But at 400 gigabit and one terabit, there is no way to do that using VCSELs, he says.
