Rick, I have read through the BB Photonics patent application on PIC's COMPOUND SEMICONDUCTOR PHOTONIC INTEGRATED CIRCUIT WITH DIELECTRIC WAVEGUIDE http://patents.justia.com/patent/20170023733 If you have read it as well, what are your thoughts is relation to how many different ways there may possibly be to create a PIC , and would this patent (if granted) be an obstacle for all others in building PIC's ? (including Lightwave)
