| 摘 要： | 在亚毫米尺度金属包覆波导研究基础上，提出了一种波长监测的新方法.实验采用自由空间耦合技术，激发了波导中对波长变化十分灵敏的超高阶导模，并以此为探针，实现了1pm波长漂移的监测.

| Abstract: | Based on the study of the metal-cladding waveguide on submillimeter scale, a new scheme for wavelength monitoring is proposed in this paper. The free space coupling technique is utilized to excite the ultrahigh-order mode to act as a probe, which is considered to be very sensitive to the wavelength change. It is experimentally demonstrated that a wavelength drift of 1pm is monitored. |
