We have fabricated optical waveguides inside the UV-transparent polymer, CYTOP, by femtosecond laser direct writing for propagating UV light in biochip applications. Femtosecond laser irradiation is estimated to increase the refractive index of CYTOP by 1.7 x 10(-3) due to partial bond breaking in CYTOP. The waveguide in CYTOP has propagation losses of 0.49, 0.77, and 0.91 dB/cm at wavelengths of 632.8, 355, and 266 nm, respectively.
我们通过飞秒激光直写技术在紫外透明聚合物CYTOP内部制备了光波导，用于生物芯片应用中紫外光的传播。据估计，飞秒激光辐照会因CYTOP中的部分化学键断裂而使其折射率增加1.7×10⁻³ 。CYTOP中的光波导在波长632.8、355和266 nm处的传播损耗分别为0.49、0.77和0.91 dB/cm。
