Sunny3999 brought the following up in the german forum.

Anadigics writes in one of their presentations: "Concurrent with developing wafer fabrication capabilities, 6-inch VCSEL epitaxial wafers were introduced into the market. In fact, IQE plc announced availability of these materials in March 2014."

And if you search for IQE you find out, that

1.) they are Key Partner of IP-IMI (http://manufacturing.gov/ip-imi.html)

2.) they produce a 64Gbs VCSEL - see the follwing quote (POET is going to produce a 50GBs VSCEL)

"VCSELs Compound semiconductor technology that enables optical interconnects include Vertical Cavity Surface Emitting Lasers (VCSELs).

VCSELs provide the primary light source for short-reach optical communication and currently provide the enabling technology for high capacity optical interconnect cables in storage area networks such as datacentres and server farms. VCSEL enabled, multimode fibre optic interconnects optimized for transmission speed at a wavelength of 850 nm are also used in high performance computing systems such as computer clusters and supercomputers.

VCSELs are an advanced laser technology geared to mass production and low cost. IQE is the market and technology leader for VCSEL products, with world record data speeds in excess of 64 GBs recently demonstrated. This is a key milestone in the adoption of photonic technologies for a wide range of data communications applications.

IQE technology leadership and reputation for operational excellence has helped secure major new high volume supply contracts, including a contract with Philips electronics in 2013."
