Dense parallel optics, more specifically 2 dimensional arrays of light communication, even more specifically the natural technological format of such as a chip-on-chip integrated array of photonics on a VLSI chip, has in the last few years gone private, so to speak. Three companies, Xanoptix, Teraconnect, and Aralight, were formed to commerciallize this technology.
The chosen product in each case was a higher channel count E/O converter than currently available twelve channel versions, which are based on a linear array of non-integrated photonics. The technology and issues with this application will be discussed.
