摘　　要：对新型聚合物光子材料杂萘联苯型聚芳醚砜硐(PPESK)波导薄膜的成膜工艺进行了系统的研究。分析了溶剂吸水性对成膜质量的影响,并通过氮气保护的方法获得了具有良好均一性的波导薄膜,其厚度一致性可优于1%,折射率一致性优于0.03%。采用棱镜耦合技术测量分析了PPESK波导薄膜的折射率、双折射、热光系数等光学特性,测量得到该材料在1310 nm波长处的损耗小于0.24 dB/cm,在1550 nm波长处的损耗小于0.52 dB/cm,表明该材料是一类性能良好的聚合物光子材料。Film preparation of a novel polymer photonic material, PPESK, was investigated systemically. The influence of solvent hydrophilicity on film quality was analized. A good waveguide film with homogeneous thickness （better than 1%） and identical refractive index （better than 0. 03%） was fabricated by nitrogen atmosphere protection. The optical properties of PPESK film, including refractive index, birefringence, thermal-optical coefficient and optical loss, were measured and characterized by prism-coupling technique, and the optical loss was measured to be lower than 0.24 dB/cm at 1310 nm, and lower than 0.52 dB/cm at 1550 nm. The results showed that PPESK was a promising photonic polymer material due to its fine optical performance.
