Microprocessor manufacturers are all the more reluctant to pursue monolithic integration because they’ve pushed up against the physical limits of the transistor design that has remained more or less consistent for more than 50 years (keeping up with Moore’s Law).

They are now facing all the extra constraints on photonics (optimizing the performance of optical components, materials used in today’s optical devices are incompatible with the processes currently used to produce microprocessors etc.): they have to make significant changes to existing semiconductor fabrication processes and designs.

Intel, IBM (« Holey Optochip »), HP (« Corona »), APACHE etc. Current projects are hybrids based on silicon tech. (chip stacking : won´t work with conventional microprocessors, which require a much denser concentration of higher-performance components), or simply too big (not an option in laptops, cellphones etc.), are desperately trying to create and integrate an on-chip laser for their design (data-carrying beam of light would be off-chip), or for the most innovative designs, complete monolithic platform is totally out of reach (eg Infinera PIC: monolithic integration of optical components only).

Future chips that use optics to communicate between cores will require on-chip lasers (for energy-efficiency tricks) like the integrated laser device created by ODIS.

Clearly, ODIS has made the biggest achievement in POET Monolithic Optoelectronic Platform with its on-chip laser. And today, POET seems to be the only innovative and patented design to support monolithic fabrication of ICs containing not only optical elements, but also analog and digital elements. For the first time an economical integration of many optical devices together with dense, high-speed analog and high-speed, low-power digital elements are possible in monolithic ICs.

Who in this forum is investing in OPL thinking Q1 2014 is a long and outrageous wait?
