POET and Foxconn collaborate on 800G and 1.6T optical transceivers
Foxconn has selected POET to supply silicon PIC optical engines for use in high-speed pluggable transceivers, which are intended to address growing demand from AI and datacentre applications
POET Technologies has announced that Foxconn Interconnect Technology (FIT), a provider of interconnect solutions for communication infrastructure and several other large, high-growth markets, has selected POET’s optical engines, which are silicon PICs, for its 800G and 1.6T optical transceiver modules.
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 datacentre networks. As part of the collaboration, POET will develop and supply its silicon PIC optical engines based on the patented POET Optical Interposer technology, while 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. “We are excited to partner with POET on this development. 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.”
Suresh Venkatesan, chairman and CEO of POET, said: “POET’s vision is to ‘semiconductorise’ photonics by integrating electronic and photonic components on the interposer to enable wafer-scale assembly. We are honoured 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, onto 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.
POET expects to complete the design of the optical engines for FIT by Q3 2024 and start optical engine production at its joint venture, Super Photonics Xiamen, by Q4 2024.
