Great article . I like the comment "several SiP suppliers have already demonstrated that this technology works, but Kozlov said that “it is up to the manufacturing engineers and business managers of these suppliers to show that SiP products can be made in high volume at a competitive cost and generate profits to fund development of next generation products. As often happens with new technologies, product sales start to ramp up just as industry expectations are starting to fade.”

As well, "Competition to such nascent silicon photonics products as already exist will continue to come from more established indium phosphide and gallium arsenide technologies. Kozlov says this competition will be fierce through the period 2016–2021: “There is not a single SiP-based product on the market that does not have an alternative made using InP and GaAs optics," he said."
