I find it interesting that on IBK website they mention HP. The patent was filed in 2012.

Potential applications include:

• POET’s technology can surpass speed limits of widely used CMOS silicon chips and is much better positioned for stacking multiple chips to increase performance;
• A functional POET device may reduce the power consumption of laptops, tablets, smartphones, servers, and/or other electronic devices by 80%;
• Leads to drastic reduction in device size and battery power consumption – Power reduction in commercial-scale server farms represents tremendous cost savings to companies like IBM, Google and Intel – In November 2011, Hewlett Packard announced that it is working with numerous chip manufacturers to create ultraefficient, low-energy servers aimed at companies running large scale remote computing operations such as Twitter and Facebook; and,
• POET can also produce an infra-red sensor for use in air, sea, ground, and space with sensitivity that is an order of magnitude higher than existing technology
