The optical engine highly embeds or places photonic devices or features (lasers, detectors, waveguides, filters, etc.) within the layer of an interposer. The device can realize the conversion and transmission of photo-electric signal.
The Optical Interposer is developed by POET, which is also a technology that POET prides itself on. Its consists of layers of materials built on a standard semiconductor wafer of any size, using standard semiconductor (CMOS) processes. The Optical Interposer utilizes a novel waveguide technology that allows the integration of electronic and photonic devices into a single multi-chip module. It also incorporates waveguides that guide and focus light, other passive devices (such as filters and gratings) and features which enable the accurate placement and integration of active devices. By applying advanced wafer-level semiconductor manufacturing techniques and novel packaging methods, the Optical Interposer eliminates costly components, assembly, alignment and testing methods employed in conventional photonics solutions. In addition to lowering costs compared to conventional devices, the Optical Interposer provides a flexible and scalable platform for a variety of photonics applications.
The Optical Engine can highly integrate drivers, laser chips, photo detectors on the interposer to be 2.5D and 3D packaging structure which provides advanced solutions of high speed, high integration and low cost.
Optical module converts digital electrical signals generated by conventional electronic devices into light waves which can be transmitted over optical fibers with higher data density, lower loss and lower cost than copper wire. Meanwhile, the light waves are detected and converted back to digital electrical signals that can be transmitted using copper or another transmission media.
