Technologies and Products

Toronto-headquartered designer, developer and manufacturer of optoelectronic devices POET Technologies has announced a novel Optical Interposer Platform, which facilitates the co-packaging of electronics and optics in a single Multi-Chip Module (MCM).

Based on its previously announced Dielectric Waveguide technology, POET’s Optical Interposer provides the ability to run electrical and optical interconnections side-by-side on the same interposer chip, at a micrometre scale. The optical interposer represents an integral part of POET’s hybrid integrated optical engines, and leverages the manufacturing processes and unique capabilities of its dielectric waveguides.

POET notes that, as the need for higher data transfer speeds at greater baud rates and lower power levels increases, optics will move increasingly closer to the source of the data, whether it be a processor, Application Specific Integrated Circuit (ASIC) or Field Programmable Gate Array (FPGA). POET’s Optical Interposer Platform enables an optoelectronic interconnect fabric to interface directly with the source of data to support high-speed optical data transfer from within the MCM.

Additionally, this technology is projected to offer cost-efficient optical interconnects, allow for a reduction in components, and reduce test and assembly steps to decrease manufacturing costs. The company believes its Optical Interposer Platform targeting 100G transceiver applications is readily scalable to 200G and 400G transceiver products with minimal incremental cost. POET also reckons the scalable architecture (in reach and speed) of this platform has the potential to provide it with a highly differentiated competitive advantage in leading-edge data communication transceiver products.

POET’s Optical Interposer has applications in a range of high-growth markets, primary among them being high-performance computing, networking, optical transceivers and transponders and automotive LIDAR systems. This platform technology is applicable to both Gallium Arsenide (GaAs) and Indium Phosphide (InP) based optical components. Optical engines for single mode transceiver modules represent the initial high-volume application for POET’s Optical Interposers.

POET adds that, consistent with prior expectations, the company continues to work toward providing engineering samples of a Receive Optical Engine to customers by the middle of 2018. This device will be fabricated leveraging the  Optical Interposer Platform.
