Tin doped indium oxide (ITO) coatings fabricated onto D-shaped optical fibers are presented as the supporting medium for Lossy Mode Resonances (LMRs) generation. The characteristic geometry of ITO-coated D-shaped optical fibers enables to observe experimentally LMRs obtained with both TM and TE polarized light (LMR(TM) and LMR(TE)). This permits to obtain a maximum transmission decay of 36 dB with a LMR spectral width of 6.9 nm, improving that obtained in previous works, where the LMRs were a combination of an LMR(TM) and an LMR(TE). Surrounding medium refractive index (SMRI) sensitivity characterization of LMR(TM) has been performed obtaining a maximum sensitivity of 8742 nm/RIU in the range 1.365-1.38 refractive index units (RIU) which overcomes that of surface plasmon resonance-based optical fiber devices presented in recent works.
本文介绍了制备在D形光纤上的掺锡氧化铟（ITO）涂层，作为产生损耗模式共振（LMR）的支撑介质。ITO涂层D形光纤的独特几何结构使得能够通过实验观察到用TM和TE偏振光获得的LMR（LMR(TM)和LMR(TE)）。这使得能够获得36 dB的最大传输衰减，LMR光谱宽度为6.9 nm，优于先前工作中获得的结果，在先前工作中LMR是LMR(TM)和LMR(TE)的组合。已经对LMR(TM)的周围介质折射率（SMRI）灵敏度进行了表征，在1.365 - 1.38折射率单位（RIU）范围内获得了8742 nm/RIU的最大灵敏度，这超过了近期工作中提出的基于表面等离子体共振的光纤器件的灵敏度。
