Wafer Scale Manufacturing

The Tru-SiPh™ platform was built from the ground up to disrupt the traditional photonics markets in multiple applications. Tru-SiPh™ is being designed into ethernet pluggable modules, into copackaged optics, into Lidar, and into biosensor applications. Using our own high volume silicon foundry, we have developed a proprietary process for embedding III-V compounds within our silicon wafers, providing a high-performance wafer scale platform with all the advantages of traditional InP based optics, but without the discrete construction and alignments which are typically used. Our proprietary technology provides unique temperature insensitive optics allowing uncooled use in most applications.


With embedded lasers, modulators and photodiodes, the architecture is extremely compact compared to other approaches and contains all necessary elements for any optical function. Resulting products are natively hermetically sealed and require no additional packaging. By bonding thin eitaxies directly to the silicon substrate, our structures outperform traditional InP based optics for thermal performance resulting in very compact long-lived active elements. Serving all applications in O- and C- band, with a variety of components (see toolbox below), the platform was designed from the ground up to be application agnostic.
