The first solid state optical filter that meets CWDM requirements (and then some). This is the way of the future. That in itself is a big deal and will capture market share because it is low cost, low energy and small footprint that can be expanded into future generations. And whether you understand it or not thermal management is efficiently enabled by the optical interposer. 

This is the tip of the iceberg and not the kind that Jack may or may not be familiar with...lol.

Focus on the technology and the growing management team. The jockey and the horse are both a good bet.
