摘要：
本研究利用假塑性的(E)-1-(((5-溴吡啶-2-基)亚氨基)甲基)萘-2-醇晶体制备了一种前所未有的、可自传导绿色荧光的有机费马螺旋光波导（FSOW）。首先将一根长1.618毫米的晶体弯曲成发夹形弯曲波导；随后采用精细的机械光子学策略，将该发夹形弯曲波导雕刻为费马螺旋几何结构，其占据的紧凑面积为330×238平方微米。FSOW中的光信号在经历两次急剧的180度转弯后仍能存活并产生光学输出。FSOW中由弯曲引起的极低光学损耗可归因于晶体光滑、无缺陷的表面形貌。开发这种能够通过急弯传导光的多功能光学元件，对于实现大规模全有机光子电路至关重要。
英文摘要：
An unprecedented organic Fermat spiral optical waveguide (FSOW) self transducing green fluorescence is fabricated using a pseudo-plastic (E)-1-(((5-bromopyridin-2-yl)imino)methyl)naphthalene-2-ol crystal. A 1.618-millimeter-long crystal is initially bent into a hairpin-like bent waveguide. Later, a meticulous mechanophotonic strategy is employed to sculpt the hairpin-like bent waveguide into the Fermat spiral geometry, covering a compact area of 330x238 um2. The optical signal in FSOW survives two sharp 180-degree turns to produce optical output. The remarkably low bending-induced optical loss in FSOW can be ascribed to the smooth-defect-free surface morphology of the crystal. The development of such versatile optical components capable of transducing light through sharp bends is pivotal for realizing large-scale all-organic photonic circuits.
