提出了一种可调谐波长滤波器，并采用紫外纳米压印技术进行了验证。它由聚合物波导中的布拉格光栅和加热电极组成。通过引入包含与光栅图案集成的波导图案的智能压印印模，大大简化了光栅的制造。利用聚合物的热光效应，通过向电极提供电功率，成功地调谐了滤波器的中心波长。在1560 nm波长处，器件的透射率下降为15 dB，3dB带宽为0.8nm。实现的热光调谐效率为0.28 nm/mW，而中心波长从1560 nm移动到1558 nm，电功耗为7 mW。
A tunable wavelength filter was proposed and demonstrated by using the UV nanoimprint technique. It consists of a Bragg grating in polymer waveguides and a heating electrode. The manufacturing of the grating was substantially simplified with the introduction of a smart imprint stamp containing a waveguide pattern integrated with the grating pattern. The center wavelength of the filter was successfully tuned by taking advantage of the thermooptic effect in polymers, which was induced by supplying electrical power to the electrode. For the fabricated device, a transmission dip of 15 dB and a 3-dB bandwidth of 0.8 nm were obtained at the Bragg wavelength of l560 nm. The achieved thermooptic tuning efficiency was 0.28 nm/mW, while the center wavelength was shifted from 1560 nm to 1558 nm with the electrical power consumption of 7 mW.
