Hybrid optical components and circuits that deal with multiple signal generation and processing are quintessential for neural networking systems. Herein, the study reports the fabrication of one such component, a hybrid directional coupler (HDC) from blue emissive (4,4′‐bis(2,6‐di(1H‐pyrazol‐1‐yl)pyridin‐4‐yl)biphenyl) (BPP) and green emissive (E)‐1‐(((5‐bromopyridin‐2‐yl)imino)methyl)naphthalen‐2‐ol (BPyIN) pseudo‐plastic molecular crystals. Initially, a BPyIN microcrystal optical waveguide (OW1) is shaped into a strained waveguide with five bends using an atomic force microscopy cantilever‐tip aided mechanophotonics approach. Later, a singly bent BPyIN waveguide (OW2) is integrated into one of the bends at the coupling region on a strained waveguide to produce a 2 × 2 monolithic directional coupler (DC). Later, this 2 × 2 DC is extended to a HDC by integrating a blue emissive BPP waveguide (OW3) at another bend on the deformed waveguide. The fabricated HDC can effectively split the incident light into three parts with different split ratios and deliver multi‐color outputs depending on the port receiving the input signal. The spontaneous generation and processing of various signals produced in the circuit helps in understanding the functioning of complex optical neural networks. The demonstration of such innovative optical components manifests their utility for diverse applications in neural networking and quantum computing systems.

用于产生、分离和转换多色输出的混合有机晶体弯曲波导网络

处理多个信号生成和处理的混合光学元件和电路是神经网络系统的典型。在此，该研究报告了一种这样的组件的制造，即一种由蓝色发射材料（4,4'-bis(2,6-di(1H-pyrazol-1-yl)pyridin-4-yl)）制成的混合定向耦合器（HDC）联苯）（BPP）和绿光发射（乙)-1-(((5-溴吡啶-2-基)亚氨基)甲基)萘-2-醇(BPyIN)假塑性分子晶体。最初，使用原子力显微镜悬臂尖端辅助机械光子学方法将 BPyIN 微晶光波导 (OW1) 成形为具有五个弯曲的应变波导。随后，将单弯曲 BPyIN 波导 (OW2) 集成到应变波导耦合区域的弯曲之一，以产生 2 × 2 单片定向耦合器 (DC)。后来，通过在变形波导的另一个弯曲处集成蓝色发射 BPP 波导 (OW3)，将此 2 × 2 DC 扩展为 HDC。所制造的 HDC 可以有效地将入射光分成具有不同分光比的三部分，并根据接收输入信号的端口提供多色输出。电路中产生的各种信号的自发生成和处理有助于理解复杂光学神经网络的功能。这种创新光学元件的演示表明了它们在神经网络和量子计算系统中的各种应用的实用性。
