Molecular crystals are emerging as a non-silicon alternative for the construction of all-organic photonic integrated circuits (OPICs). The advent of flexible molecular crystals and the development of atomic force microscopy tip-based mechanical micromanipulation (mechanophotonics) techniques facilitate the construction of many proof-of-principle OPICs. This article validates the reason for using organic crystals as alternate non-silicon materials for OPIC fabrication. It also guides the readers by introducing several crystal-based photonic modules and OPIC prototypes, their passive and active light transduction potentials, and the possibility of implementing well-known photo-physical concepts optical energy transfer and reabsorbance mechanisms. There is also an urgent need to develop a suitable technique for creating geometrically and dimensionally well-defined organic crystals displaying photonic attributes. Finally, the goal should be to build a library of selected optical crystals to facilitate the construction of OPICs with a pick-and-place approach.
分子晶体正逐渐成为构建全有机光子集成电路（OPIC）的一种非硅替代方案。柔性分子晶体的出现以及基于原子力显微镜探针的机械微操纵（机械光子学）技术的发展，推动了许多原理验证型OPIC的构建。本文验证了使用有机晶体作为OPIC制造的替代非硅材料的原因。它还通过介绍几种基于晶体的光子模块和OPIC原型、它们的被动和主动光转导潜力，以及实现著名的光物理概念——光能转移和再吸收机制的可能性，为读者提供指导。迫切需要开发一种合适的技术，以制造出具有光子属性、几何形状和尺寸定义明确的有机晶体。最后，目标应该是建立一个选定光学晶体的库，以便采用拾取和放置方法来促进OPIC的构建。
