“…It must be noted that the primary goal of this experimental part was to reveal the effect of t on ITO-LMR sensor performance in both optical and EC domains, as well as cross-domain interactions such as electro-optical modulation. We assume that both Al 2 O 3 and SiO 2 used in the experimental and numerical investigations, respectively, provide optical properties similar to those elicited by biomolecules grafted on the ITO sensor surface and may be considered as the reference materials to verify the performance of the label-free sensing concept. , The Al 2 O 3 used in the experimental part, in contrast to SiO 2 , can be deposited in a highly controllable way using ALD at low temperatures, i.e., with no temperature-induced effect on ITO film, which would possibly disturb the analysis of the dielectric-film-coated ITO-LMR device. However, SiO 2 , in turn, shows a slightly lower dielectric constant than Al 2 O 3 , which allows for better identification of the impact of E on the modulation of the ITO’s optical properties .…”

“…Electro-optical sensors are also considered for label-free sensing applications, especially in biosensing. , However, to date, no detailed study has been conducted concerning the impact of a layer formation on the thin film’s surface on the sensor’s performance in both domains. It is known that growth of a biological or chemical layer disturbs electrode–electrolyte charge transfer in the EC domain. , The forming layer also changes the distribution of the electromagnetic field and guiding conditions for lossy modes in the optical domain.…”

“…All-fiber refractive index (RI) sensors offer many advantages, such as insusceptibility to electromagnetic interference, light weight, small size, corrosion resistance, and high sensitivity; thus, they are widely used in biochemical sensing [1][2][3]. Recently, several types of fiber optic sensors based on fiber Bragg gratings [4,5], long period gratings (LPFG) [6,7], Fabry-Perot interferometers [8,9], fiber optic Sagnac interferometers [10,11], Michelson interferometers [12,13], and Mach-Zehnder interferometers (MZI) capable of RI detection have been proposed [14][15][16].…”
