Future upgrades of the CERN Experiments and Accelerators require optical links capable of handling the large data volume generated in particle detectors and beam position (BPMs) sensors. Silicon Photonics optical transceivers are a promising candidate to process the required data rate as well as efficiently operate in the harsh radiation environment. We present the experimental characterisation of silicon modulators together with demonstration of optical transmitters based on custom designed Silicon Photonics integrated circuits.

“…In high-energy physics (HEP) experiments, the data transmission rate from the detector to the back-end stages is increasing [1][2][3][4]. In this field, 4-level pulse-amplitude-modulation (PAM4) is a commonly used data modulation scheme [5][6][7].…”

In this paper, a decision feedback equalizer (DFE) re-decision algorithm for a 6-level pulse-amplitude-modulation (PAM6) high-speed transceiver is proposed. PAM6 is a two-dimensional (2D) modulation. The four outer points are not used in the 2D constellation diagram to reduce the output power. Although the four outer points will not be modulated, they may be encountered during demodulation. This paper considers the above situation and theoretically analyzes the DFE module under the additive white Gaussian noise (AWGN) channel. Compared with the traditional pipelined DFE structure, the proposed algorithm can help solve the four outer points in PAM6. A serializer/deserializer (SerDes) simulation system is built based on a field programmable gate array (FPGA), and the performance of the proposed algorithm is carried out on the simulation system. According to this proposed algorithm, the symbol error rate (SER) of the PAM6 SerDes system can be reduced, and the system performance can be improved. When the DFE tap coefficient is 0.50 and the signal-to-noise ratio (SNR) is 22.0 dB, the proposed algorithm can additionally correct 8.18 % of erroneous symbols. When the DFE tap coefficient is 1.00 and the SNR is 22.0 dB, the proposed algorithm can additionally correct 17.30 % of erroneous symbols.

“…The second generation CERN-designed PIC (PICv2) was fabricated on the IMEC iSiPP50G platform. PICv2 allows the continued study of radiation tolerance of the updated fabrication process and the study of the full optical link system concept [6]. PICv2 contains many structures: Mach-Zehnder Modulators, Ring Modulators (RMs), Ge photodiodes, and Si waveguides of different lengths.…”

Silicon photonics technology promises significant improvements for fibre optic links of future upgrades of HEP experiments. Such systems will require high levels of radiation tolerance and silicon photonics modulators have been shown to be very robust when exposed to high levels of radiation under certain conditions. We demonstrate for the first time that changing the temperature of ring modulators during or after irradiation can significantly improve their performance.
