Pad, Tablet and Cloud OS-type PC devices — Demand continues to surge for tablet-class devices, and the market for tablet PCs built on cloud-based services is expanding. Examples of devices key to this market are DRAM and logic circuits. These markets are projected in 2015 at $43.6 billion and $97.6 billion, respectively. Within such devices, POET’s platform is anticipated to allow optical onchip and chip to chip communications and other optical devices like VCSELs which are used in new sensing paradigms like gesture recognition. This is expected to reduce the power usage and increase functionality.
