Lossy Mode Resonance (LMR) Based Fiber Optic Sensors: A Review

In the past few decades, surface plasmon resonance (SPR) phenomenon along with optical fiber technology has emerged as a major area of research among the fiber optic sensing research groups. On the other hand, lossy mode resonance (LMR) is another kind of resonance phenomenon recently exploited for fiber optic sensing. LMR has several advantages over the well established SPR such as, free from specific polarization of light and capability of multiple LMR generation. Since LMR phenomenon is nascent for researchers and there are no review articles available till date, in this paper, we review the LMR phenomenon in applications involving sensing and wavelength filtering.
