Circularly-Polarized Optoelectronic Logic Gates

Optoelectronic logic gates, key components in optical computing and optoelectronic integration, are promising for advancing computing performance in the post-Moore era. Nonetheless, state-of-the-art multifunctional optoelectronic logic gates still depend largely on complex regulation, showing restricted functionality and intricate configuration. Circularly polarized light offers a promising route toward highly integrated multifunctional optoelectronic logic gates with its high-dimensional optics. However, existing circularly-polarized logic gates are hampered by insufficient discrimination ability and difficulty in adjusting functionality, hindering their applications. Here, a chirality-sensitive photoelectric conversion strategy is demonstrated, and based on which a series of circularly-polarized optoelectronic logic gates are constructed-encompassing the majority of logic operations. These devices exhibit an photocurrent dissymmetry factor of 1.86, underpinning their application in efficient image processing tasks, including stylization and edge extraction. Furthermore, their utility is extended to simulating max-pooling and realizing chiroptical signal processing with high recognition accuracy. This work effectively integrates chiroptics and electronics, paving the way for expanding the horizons of optical computing.
