“The low loss coupling of light from a laser into our waveguides (which are additionally configurable as Coarse Wavelength Division Multiplexing (CWDM) multiplexers or de-multiplexers) through passive wafer scale placement techniques and then into fiber demonstrates the complete functionality of the Optical Interposer platform technology.  Moreover, we believe our wafer scale integrated athermal CWDM filters represent an industry first,” commented Dr. Suresh Venkatesan, Chairman & CEO. “With optical losses at a fraction of that of other materials, our waveguides and filters enable the fabrication, assembly and testing of integrated optical engines at wafer-scale, providing maximum flexibility across a broad range of applications, from  datacom to co-packaged optics.”

Reducing optical losses reduces heat. And the heat that is generated is efficiently channeled away from critical heat sensitive waveguide filters. The laser power requirements becomes greatly reduced which again is critical in reducing the source of heat. This is what is required to advance the data capacity of optical engines. And it is done at the very low cost that industry is looking for.

This is a big deal and will generate big deals. And I suspect those big deals are in the works. What is happening with DL is I think a consequence of POET having the solution that industry needs and I think it is likely that the jockeying for position of ownership has started.
