本文提出了光子生物有机多相结构，用于具有多级逻辑元件的集成薄膜电子网络，通过手性生物材料的可重构光子带隙进行多级计算。在此，受具有高效信息集成和计算能力的人工智能系统的启发，将手性向列型纤维素纳米晶体的光子活性介电层与印刷的p型和n型有机半导体相结合，作为一种双功能逻辑元件。这些自适应逻辑元件能够在具有不同光子能量以及活性介电层的不同光子带隙的光下触发定制的量化电输出信号。双功能结构能够在光子带隙（由手性向列螺距的膨胀/收缩控制）和光子能量（由互补有机半导体层的光吸收波长控制）的重复变化时实现复杂的存储行为，有效地呈现出可重构的三值逻辑响应。这种概念验证的生物辅助多值逻辑结构为集成人机界面的低功耗光学信息处理提供了一种光学计算系统。
Photonic bio-organic multiphase structures are suggested here for integrated thin-film electronic nets with multilevel logic elements for multilevel computing via a reconfigurable photonic bandgap of chiral biomaterials. Herein, inspired by an artificial intelligence system with efficient information integration and computing capability, the photonically active dielectric layer of chiral nematic cellulose nanocrystals is combined with printed-in p-and n type organic semiconductors as a bifunctional logical element. These adaptive logic elements are capable of triggering tailored quantized electrical output signals under light with different photon energy and at the different photonic bandgaps of the active dielectric layer. The bifunctional structures enable complex memory behavior upon repetitive changes of photonic bandgap (controlled by expansion/contraction of chiral nematic pitch) and photon energy (controlled by light absorption wavelength of complementary organic semiconductor layers), exhibiting effectively a reconfigurable ternary logic response. This proof-of-concept bio-assisted multivalued logic structure facilitates an optical computing system for low-power optical information processing integrated with human-machine interfaces.
