The POET Optical Interposer™
Wafer-level integration of electronics and photonics

The POET Optical Interposer™ utilizes a novel waveguide technology that allows the integration of electronic and photonic devices into a single multi-chip module. By applying advanced wafer-level semiconductor manufacturing techniques and novel packaging methods, POET’s Optical Interposer eliminates costly components, assembly, alignment and testing methods employed in conventional photonics solutions. In addition to lowering costs compared to conventional devices, POET’s Optical Interposer provides a flexible and scalable platform for a variety of photonics applications ranging from data centers to consumer products.



What is an Optical Interposer?

Interposers have been used for several years to allow electronic devices (microprocessors, memory devices, etc.) to communicate with each other via high-speed metal traces embedded in a semiconductor wafer. POET invented methods for embedding or placing photonic devices or features (lasers, detectors, waveguides, filters, etc.) within the top layer of an interposer, allowing high speed communication between electronic and photonic devices.



The POET Optical Interposer consists of layers of materials built on a standard semiconductor wafer of any size, using standard semiconductor (CMOS) processes. The bottom layers include the high-speed metal traces found in electronic interposers, while the top-most layers incorporate waveguides that guide and focus light, other passive devices (e.g., filters and gratings) and features which enable the accurate placement and integration of active devices.



The POET Optical Interposer is a platform technology. It offers the ability to produce Opto-electronic devices of various kinds in high volumes with the efficiencies of wafer-level processing. The low-cost integration scheme and scalability of the POET Optical Interposer brings value to any device or system that integrates electronics and photonics, including some of the highest growth areas of computing, such as Artificial Intelligence (AI), the Internet of Things (IoT), autonomous vehicles and high-speed networking for cloud service providers.



What makes the POET Optical Interposer so unique?

Low-loss, single mode passive waveguides with unique properties that facilitate device integration on any size silicon wafer - adaptable to a wide range of uses

Total CMOS compatibility for exploiting true wafer-scale assembly - driving down complexity and cost

An elegant design and assembly scheme that provides maximum flexibility and scalability
