    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. In these new LMR sensors, if the non-metallic nanocladding of an optical waveguide fulfills the conditions explained in this work, coupling of light to the cladding modes happens at certain resonance wavelengths, which enables the use of LMR devices as refractometers and opens the door to diverse applications such as in biology and proteomics research. These highly sensitive refractometers have already shown sensitivities higher than 20,000 nm/RIU or 5x10-7 RIU and, given the youth of this field, it is expected to achieve even better values.

    Multi-sensing platform design with a grating-based nanostructure on a coverslip substrate
    (Springer, 2023) Imas GonzĆ”lez, JosĆ© Javier; Del Villar, Ignacio; Ruiz ZamarreƱo, Carlos; Mukhopadhyay, Subhas C.; MatĆ­as Maestro, Ignacio; IngenierĆ­a ElĆ©ctrica, ElectrĆ³nica y de ComunicaciĆ³n; Institute of Smart Cities - ISC; Ingeniaritza Elektrikoa, Elektronikoaren eta Telekomunikazio Ingeniaritzaren
    Two different thin film designs with a grating pattern are simulated on a soda lime coverslip, which acts as optical waveguide, with the purpose of generating both a lossy mode resonance (LMR) in transmission and reflection bands. This way both phenomena can be made sensitive to different parameters, leading to a multi-sensing device. The first design consists of a grating patterned in a SnO2 thin film deposited on the coverslip. The performance of the device in both transmission and reflection is numerically studied in air for different values of the grating pitch. Small grating pitches (in the order of the Āµm) are more suitable for generating the reflection bands while larger values (500 Āµm or more) are required to produce the LMR, when the reflection bands are no longer visible. Due to the inability to obtain both phenomena with this design, a second design is assessed, where the grating is combined with a section of constant thickness. In this case the desired response is obtained, which opens the path to use this device for multi-sensing applications, measuring several parameters at the same time.

    Nanocoated optical fibre for lossy mode resonance (LMR) sensors and filters
    (IEEE, 2015) Del Villar, Ignacio; Arregui San MartĆ­n, Francisco Javier; Corres Sanz, JesĆŗs MarĆ­a; BariĆ”in Aisa, CĆ”ndido; Goicoechea FernĆ”ndez, Javier; Ruiz ZamarreƱo, Carlos; ElosĆŗa Aguado, CĆ©sar; HernĆ”ez SĆ”enz de Zaitigui, Miguel; Rivero Fuente, Pedro J.; Socorro LerĆ”noz, AbiĆ”n Bentor; Urrutia Azcona, Aitor; SĆ”nchez ZĆ”bal, Pedro; Zubiate Orzanco, Pablo; LĆ³pez Torres, Diego; Acha MorrĆ”s, Nerea de; Ascorbe Muruzabal, JoaquĆ­n; MatĆ­as Maestro, Ignacio; IngenierĆ­a ElĆ©ctrica y ElectrĆ³nica; Ingeniaritza Elektrikoa eta Elektronikoa
    Nanometer scale coatings with a complex refractive index deposited on optical fibre permit to obtain attenuation bands in the transmission spectrum, whose central wavelength coincides with the moment when a mode guided in the optical fibre cladding starts to be guided in the coating. Due to the complex refractive index of the coating, the guided mode is a lossy mode. Consequently, these attenuation bands receive the name of lossy mode resonances. This phenomenon can be used for development of ultra-high sensitivity photonic devices (for detection, among others, of volatile organic compounds, pH and refractive index) or for optical filtering. In this work, rules for adequate design are indicated based on numerical results obtained with FIMMWAVE and on experimental results that corroborate the theoretical predictions.
