摘要
有机单晶由于其较低的光传输损耗和可调谐的光学特性,在光限制和光波导领域显示出广阔的应用前景.单一的一维或二维(1D或2D)光波导晶体在有机光子学中具有单一功能的局限性.在这项工作中,我们通过精心设计的顺序生长方法制造了一种芯片状的有机异质结构.通过调节各有机组分的浓度,依次进行溶液自组装、刻蚀和外延自组装过程,完成有机微纳结构的定向生长.值得注意的是,所制备的芯片状有机异质结构由1D/2D光波导晶体组成,可实现多方向光子传输和多端定向光信号输出.此外,芯片状异质结构独特的二维光波导特性为构建微/纳米级输出光信号的编码形式提供了机会.
Organic single crystals show broad application prospects in the field of optical confinement and waveguides due to their low optical transmission loss and tunable optical properties.Individual one-or two-dimensional(1D or 2D)optical waveguide crystals have the limitations of a single function in organic photonics.In this work,a chip-like organic heterostructure was fabricated using an elaborately designed,sequential growth method.By regulating the concentration of each organic component,the processes of solution self-assembly,etching,and epitaxial self-assembly are successively performed to complete the directional growth of organic micro/nanostructures.Notably,the as-prepared chip-like organic heterostructure is composed of 1D/2D optical waveguide crystals,which can realize multidimensional photon transportation and multi-terminal directional optical signal output.Furthermore,the unique 2D optical waveguide properties of the chip-like heterostructures offer opportunities for constructing the encoding form of the output optical signal at the micro/nanoscale.
