MERLIN

Next-generation multi-beam terabit telecom satellites – Photonics in the satellite

Objective

New multi-beam tera-scale capacity satellites will require a disruptive approach to address digital on-board processors that rely on electronics which consume space, power and cost and reach their capacity saturation. The disruptive solution must combine scalability, technical feasibility, power-efficiency and cost-effectiveness. MERLIN aims to provide this solution realizing multi-gigabit optical interconnect with a unique combination of low-power high-bandwidth multimode GaAs VCSELs and PDs, low-power radiation-hardened BiCMOS driver ICs, and radiation-hardened multi-core fibers. MERLIN will integrate these technologies on a space-grade photonic integration capable of providing ruggedized transceiver modules with a record-high 150-Gb/s throughput and record-low <10-mW/Gbps energy consumption. The main objectives in the project are:

  • Advanced electro/photonic integration platform for harsh environment
  • Multi-core compatible and energy-efficient vertical GaAs 850-nm VCSEL and PD arrays
  • Low-power multi-channel VCSEL drivers and TIA ICs
  • Radiation-hard multi-core multi-mode fibres

IHP's Contribution

In the MERLIN project IHP is responsible for the design, fabrication and prototype testing of low-power radiation-hard electronic ICs for co-integration with the photonic devices. IHP will develop multi-channel VCSEL driver IC arrays and TIA receiver arrays operating at up to 25 Gb/s per channel and supporting the independent operation control and the embedded intelligence for autonomous operation. The ICs will be fabricated with IHP's high-performance 0.25-µm SiGe:C BiCMOS technology.
