Hydroxypropyl Cellulose Coated Assembled Microfiber Loop Sensors

摘要：

　　Assembled optical structures formed by heavily bending,twisting or coiling microfibers can not maintain their geometries for a long time.In this work,we demonstrate stabilized microfiber structures via high-substituted hydroxypropyl cellulose (H-HPC) coating.The feasibility of the method is verified by coating a loop sensor formed by heavily twisting a silica microfiber.The spectrum measurement over 2.6 hours demonstrates good stability of the coated structure in aqueous solutions.The HPC coating can maintain strong evanescent-field interaction and the coated sensor presents a RI sensitivity of~2600 nm/RIU.The present technique is greatly beneficial for long-term working of microfiber sensors and the further development of integrated microphotonic platforms with complex structures.
