"it is the application of BBPhotonics to dielectric waveguides which includes a spot size conversion for single mode applications and the removal of the requirement for lenses."
Thanks FJ, I am betting I am not the only one that doesn't comprehend where this explanation fits in with POET or with Lightwave. What is the application for this component of a PIC? Is it to route the light from the waveguide to the fiber? Are gain materials used?
