Silicon PICs will FIT into 800G and 1.6T optical transceiver modules

POET Technologies Inc., Toronto-based developers of the POET Optical Interposer and Photonic Integrated Circuits (PICs) for the data center, telecommunication and artificial intelligence markets, announced that Foxconn Interconnect Technology (FIT), has selected POET’s optical engines, which are silicon photonics integrated circuits (Silicon PIC), for its 800G and 1.6T optical transceiver modules. A leading global manufacturers of interconnect technologies, FIT is a market leader of solutions for communication infrastructure and several other large, high-growth markets.

POET and FIT have entered into a collaboration to develop 800G and 1.6T pluggable optical transceiver modules using POET optical engines with an aim to address the growth in demand from cutting-edge AI applications and high-speed data center networks. As part of the collaboration, POET will develop and supply its silicon photonics integrated circuit optical engines based on the patented POET Optical Interposer technology and FIT will design and supply the high-speed pluggable optical transceivers for delivery to some of the largest end customers in the world.

“The growth in demand from emerging applications such as artificial intelligence and machine learning requires continuous innovation to keep pace with power and cost requirements,” said Joseph Wang, CTO at FIT. “POET’s hybrid-integration platform technology will enable us to use best-of-breed components and ramp to high volume at a much faster pace and in a cost-efficient manner.”

Vision is to ‘semiconductorize’ photonics

“POET’s vision is to ‘semiconductorize’ photonics by integrating electronic and photonic components on the interposer to enable wafer-scale assembly,” said Dr. Suresh Venkatesan, POET’s chairman & CEO. “We are honored to work with an industry leader like FIT, capable of ramping to high volume production with its expertise in transceiver design and manufacturing. We look forward to expanding our collaboration to future projects once this initial project is complete.”


POET’s transmit optical engines integrate externally modulated lasers (EMLs), EML drivers, monitor photodiodes, optical waveguides, thermistors and an optical multiplexer, where applicable, on to an optical interposer-based PIC. The receive optical engines integrate high-speed photodiodes, transimpedance amplifiers, optical waveguides and optical demultiplexers, where applicable. All components are passively assembled on the interposer at wafer scale using standard pick-and-place semiconductor equipment. Passive alignment of the photonic elements and use of high-speed RF traces between the electronic and photonic components to avoid wire-bonds are two hallmarks of the technology.
