We review the most important achievements published in the last five years in the field of
silicon-based optical biosensors. We focus specially on label-free optical biosensors and …

This review brings about a comprehensive presentation of the research on interferometric
transducers, which have emerged as extremely promising candidates for viable, truly …

In this paper, we report on the design, fabrication, and characterization of a photonic circuit
for biosensing applications. Silicon oxynitride with a bulk refractive index of 1.66 is the core …

The development of optical biosensors based on silicon dioxide or silicon nitride
transducers requires the chemical activation of their surface to achieve stable, repeatable …

Refractive index sensors based on surface plasmon resonance (SPR) promise to deliver
high sensitivities. However, these sensitivities depend on the derivative of the monitored …

A refractive index sensor based on the Mach-Zehnder interferometer (MZI) with double-slot
hybrid plasmonic waveguide is proposed. Numerical simulation shows that the dispersion …

We present monolithically integrated waveguide with thin isolated layers of dielectric
material, which ensure efficient emission of guided light in multiple optical windows. The …

In this paper, we investigate the optimized parameters of bent part coupling silicon oxynitride
micro-racetrack optical resonators coupled to a straight waveguide, for an efficient design of …

In this paper, an on-chip refractive index (RI) sensor based on the asymmetric Mach–
Zehnder interferometer (MZI) is proposed for sensitivity enhancement. The outstanding …
