From last post and SBIR final phase II award;

Remember Phase III is produced product and what comes after product is sales=$$$

This is what US AIR FORCE says about POET.

Just saying

The optoelectronic chip developed here will outperform other optical fabrics by an order of magnitude at a substantially reduced cost. Therefore market penetration is assured. This technology platform will also solves other problems related to optical routers such as wavelength conversion, optical DRAM and high speed logic interconnections. This approach to switching fabrics will establish a new direction in the industry.
