Researchers at the Institute of Semiconductors of the Chinese Academy of Sciences in Beijing have reported a four-core optical computing chip that reaches 65 TOPS while supporting 124-channel parallel processing. The work focuses on multi-feature fusion enhancement, a task that benefits from fast, highly parallel hardware.
According to the report, the chip combines coherent interference with wavelength-division multiplexing. That pairing allows multiple optical channels to operate in parallel, helping the device handle more information at the same time than a conventional single-channel approach.
The multi-core design is a notable part of the demonstration. By using four cores in one optical computing platform, the researchers showed how photonic hardware can scale up throughput while keeping the system aimed at complex feature-processing workloads.
The result highlights continued progress in optoelectronic computing, where light-based processing is being explored as a way to boost speed and parallelism. A chip delivering 65 TOPS with 124 channels suggests growing potential for optical processors in advanced signal and data-processing applications.
