Abstract (in Japanese) (See Japanese page) 
(in English) The author reviews optical interconnect-related topics reported at ECOC2023. It seems that there was a lot of interest in DSP, which has the highest power consumption among the components of optical transceivers. There was a debate with analog devices, such as a CDR, and optical processors as alternative candidates. Power saving of DSP can be expected as the CMOS process node becomes narrower. In order to increase the transmission capacity, there was a debate as to whether transponders should be implemented using one wavelength or multi wavelengths. The index of cost/bit suggests that a higher baud rate per wavelength is better. On the other hand, there are technical challenges to expand the bandwidth of optical modulators, optical receivers, and ADC/DAC. As the bandwidth of Si modulators is almost reaching its physical limit, there are two approaches: adopting a coherent technology to achieve a higher data rate and increasing a baud rate of IM-DD by heterogeneously integrated high-speed modulators on Si platform. Several different high-speed optical modulators are demonstrated where the adoption of GeSi platform was reported and optical modulators using several different ferroelectric materials are also reported. Membrane devices are attractive to realize low power operation owing to high optical confinement and achieve highly efficient optical coupling between InP and Si waveguides. The author reported an ultra-compact VCSEL-based optical transceiver for CPO, which has been researched in the NICT B5G BRIGHTEN project.
