JePPIX MPW Platforms

JePPIX offers platforms created from InP integrated photonics and the TriPleX platfrom, although not Silicon photonics. Each has there own distinctive advantage and a comparison table is offered below.

Select the technology that suits your needs best. If you have an idea on what building blocks are required for your circuit, use the comparison table below to help you in your selection. JePPIX members receive independent advice to help in making the right selection. Contact us to discuss the possibilities and help you make your selection.

If additional expert advice is required to compare different foundry processes and their adequacy to the target application, this can be provided by professional design houses.

TriPlex Platform

The TriPleX platform offers low-loss straight waveguides, bends, S-bends, offsets, splitters, spot size converters, lateral tapers and thermo-optic phase shifters.

For example, combinations of these building blocks allow the creation of microwave photonics ASPICs by combining Mach-Zehnders and micro ring resonators. The current platform has guaranteed losses below 0.5 dB/cm. Further technical information on Triplex MPW’s is posted on the new Lionix International website

InP Platform

JePPIX offers a low cost access to the production of InP based chips.

InP offers amplification and laser sources which are monolithically integrated on chip. No need for complex assembly steps. Additionally InP offers efficient modulators and detectors as well as a broad range of passive waveguide structures and devices. The latest capability overview is shown in the table below.

PDK extension for SMART Photonics

Besides the building blocks shown below, a PDK extension is available via TU/e: tuesmartx. This PDK contains TU/e extension building blocks for SMART Photonics. Such building blocks are used in the same way as regular building blocks from the foundry.

Examples of building blocks provided by tuesmartx are MMI couplers with different splitting ratios, (tunable) lasers and arrayed waveguide gratings. It requires the (n+) MPW PDK from SMART Photonics. The extension is free for MPW use.
