Using near-field microscopy, the performance of dielectric-loaded plasmonic waveguide-ring resonators (WRRs) operating at telecom wavelengths is investigated for various waveguide-ring separations. It is demonstrated that compact (footprint approximately 150 microm(2)) and efficient (extinction ratio approximately 13 dB) WRR-based filters can be realized using UV-lithography. The WRR wavelength responses measured and calculated using the effective-index method are found in good agreement.
利用近场显微镜，研究了在电信波长下工作的介质加载等离子体波导环谐振器（WRR）在不同波导 - 环间距时的性能。结果表明，使用紫外光刻技术可以实现紧凑（占地面积约150微米²）且高效（消光比约13分贝）的基于WRR的滤波器。通过有效折射率法测量和计算得到的WRR波长响应结果吻合良好。
