Huawei patent for optical computing chip system and data processing technology

On August 14, 2019, Huawei has applied for a patent, optical computing chip, system, and data processing technology, which was passed on February 2, 2021, with publication number CN112306145A in China.

The patent description discloses that this technology can be used in the field of Artificial Intelligence (AI) to recognize the image, speed, and natural language processing in deep learning.

The light computing chip includes a light source array, a first concave mirror, and a modulator array to complete the modulation and calculations required. The light source array is located on the focal plane of the object plane of the first concave mirror. The modulator array is located on the image focal plane of the first concave mirror.

The light source array is used to generating a first light signal according to the first data. The first concave mirror is used for outputting a first reflected light signal according to the first light signal.

The modulator array is used to receive the first reflected light signal, obtain the first spectral distribution data according to the first reflected light signal, and modulate the first frequency spectral surface distribution data on the modulator array.

Comparing this patent technology with traditional microelectronic chips, optical computing in some applications has been greatly enhanced including calculation speed.

Currently, optical computing chips are available for inventors related to Tsinghua University (except- Huawei). At the present, not much information regarding this technology has disclosed.
