Periodic Reporting for period 1 - SIPHO-G (Advanced GeSi components for next-generation silicon photonics applications)
Okres sprawozdawczy: 2021-01-01 do 2022-12-31
In WP2 the development of frameworks to model optical properties of QCSE and APDs is ongoing at nextnano and IMEC, and an initial PDK was completed by LUCEDA. Nextnano’s QCSE model was tested against the samples provided by IMEC and deliverable D2.1 “Report on device modelling and PDK” was submitted. WP2 has a slight delay with T2.1 that will be compensated with the extension of the project.
Processing development to optimize the epitaxial growth for QCSE and APD devices in WP3 is ongoing according to schedule for APD devices and QCSE modulators operating in O-band (IMEC). The work on the C-band modulators by AMBEL is slightly delayed but picked-up by the end of 2022. A revision of deliverable D3.1 “Report on the epitaxial growth development for QCSE modulators and for APDs” has been resubmitted.
The integration of these components in the silicon photonics integration platform is ongoing at IMEC and designs of integrated components are included in the PIC design vehicle. In WP4 measurements of device parameters and evaluation of their performance is ongoing. A few issues occurred on integrating the components into the photonics platform which led to a delay in processing of the QCSE samples. Mitigations have been identified and will be implemented in Run #2. Therefore, the deliverable D4.1 “Report on building block development from Run #1” is also delayed.
In WP5 the SIPHO-G Demonstrator Run #1 is completed. The first demonstrator circuits have been designed, fabricated and assembled together with the first generation Electronic Integrated Circuit (EIC) that has been designed by GF. Testing of the assembled demonstrators will be performed by MLNX and Ericsson. The work on the demonstrators is on track, the principle of operation of the EAM-based multi-level transmitter and coherent transmitter, respectively, was investigated in circuit-level simulations by MLNX, Ericsson worked on the transceiver specifications and started the study for the design and realization of the fronthaul networks demonstrators, and AUTH has developed a mathematical framework towards investigating the scalability credentials of the proposed crossbar architecture. The deliverable D5.1 “Specifications of transceiver modules and design report of Run #1” was submitted and D5.2 “Testbed development, definition of testing methodologies and test plan” will be submitted with a few months delay.
The Dissemination, exploitation and innovation management (WP6) is ongoing. Dissemination material (templates, website, ...) as well as exploitation and innovation content were on time. SIPHO-G results have been published in about 10 scientific conferences/journals and a plan for future publications has been prepared. The exploitable results have been identified during the first 12 months and are being verified and updated every 6 months. The list of exploitable results and their descriptions together with communication and dissemination activities are part of deliverable D6.1 that has been submitted with a few months delay.
After 24 months in the project, a 1st run is completed and being characterized as we speak. All supporting activities (from the PDK, over to the demonstrator and its testing activities) are ongoing, and continuing on the path of completion.
