Quantized quasinormal-mode theory of coupled lossy and amplifying resonators [PDF]

Physical Review A, 2022
In the presence of arbitrary three-dimensional linear media with material loss and amplification, we present an electromagnetic field quantization scheme for quasinormal modes (QNMs), extending previous work for lossy media [Franke et al., Phys. Rev. Lett. 122, 213901 (2019)].

Fiber-optic Lossy Mode Resonance Sensors [PDF]

Procedia Engineering, 2014
In the last 4 years, experimental evidences about the potential use of optical sensors based on Lossy Mode Resonances (LMR) have been presented in the literature. These LMR sensors have some similarities with Surface Plasmon Resonance (SPR) sensors, the gold standard in label-free, real-time biomolecular interaction analysis.

Ammonia Gas Optical Sensor Based on Lossy Mode Resonances

IEEE Sensors Letters, 2023
This letter presents the fabrication and characterization of an ammonia (NH 3) gas optical sensor based on lossy mode resonances (LMRs). A chromium (III) oxide (Cr 2 O 3) thin film deposited onto a planar waveguide was used as LMR supporting coating. The obtained LMR shows a maximum attenuation wavelength or resonance wavelength centered at 673 nm. The

Generation of Lossy Mode Resonances With Absorbing Thin-Films [PDF]

Journal of Lightwave Technology, 2010
The generation of lossy mode resonances with absorbing thin-films is analyzed with electromagnetic theory. The main differences with surface plasmon resonances are presented and some rules are given towards an optimum design of sensing devices based on absorbing thin-film coated silica substrates.

Design rules for lossy mode resonance based sensors [PDF]

Applied Optics, 2012
Lossy mode resonances can be obtained in the transmission spectrum of cladding removed multimode optical fiber coated with a thin-film. The sensitivity of these devices to changes in the properties of the coating or the surrounding medium can be optimized by means of the adequate parameterization of the coating refractive index, the coating thickness ...

Lossy Mode Resonance Based Fiber Optic Sensor for the Detection of Acetone Concentration

Journal of Biomedical Photonics & Engineering, 2023
Diabetic ketoacidosis (DKA) is a serious complication arising due to the shortage of insulin that allows blood sugar into cells to be used as energy. As a result, the liver begins to break down fat for energy, thus producing acids called ketones.

Lossy mode resonance generation with perovskite-coated photonic crystal fiber for sensing applications

Results in Physics, 2023
Two-dimensional polymer perovskite (CH3NH3PbI3) has very potential properties in sensing applications. Hence, for high sensitivity, a lossy mode resonance refractive index sensor based on perovskite coating is proposed. The sensor uses a photonic crystal
