Photonic transceivers will be designed and optimized for inter-chip on-board optical communications. Parallelization of data to address high bandwidth density requirements for on-board communication will be implemented in a CMOS compatible platform using wavelength division multiplexing which provide an extra degree of freedom for adaptivity of energy consumption in optical transceivers. Energy efficient optical modulators for transmitter side and proper photonic filters to demultiplex incoming optical signals as well germanium photodiodes will be realized for receiver side.

Role within the CRC 912

Projects A07 (Ellinger) and A11 exchange the results about the transceiver design. Project A11 will provide the modulator and photodiode A07 (Ellinger) which will be used for the realization of high speed driver and transimpedance amplifier circuits. Project A07 (Ellinger) provides the necessary information about the requirements of having more energy-efficient photonic transceivers to A11. Projects A10 (Bock) and A11 exchange information about packaging requirements which will be used for the design of the proper couplers and tapers for coupling light from/to transceivers to/from waveguides. Characterization experience developed in A05 (Plettemeier) will be used in this project to measure the performance of the designed components. Therefore, a close collaboration is planned results from A05 (Plettemeier) to A11. Project A11 provides the required information about the channel model and link budget to project A03 (Jorswieck), in order to be used for efficient design of network coding for the links. Also, will receive models and fundamental limits for physical layer network coding to be used for optimal design of optical links. Parameters of the photonic links will be provided to A02 (Fischer) and optimized distribution of physical optical links will be received from A02 (Fischer). Performance parameters of photonic transceivers in terms of delay, power consumption and energy efficiency will be provided to A04 (Nagel) to be used for the simulator. Simulation results regarding the performance of the photonic transceiver components in the context of parallel applications are provided by A04 (Nagel).
