A Concise Review of the Progress in Photonic Sensing Devices

Abstract

Photonic sensing devices have become increasingly important in various fields such as agriculture, medicine, biochemical sensing, and manufacturing. They are highly sensitive and can classify minor changes in the physical and chemical properties of the ambient medium with high precision. This makes them practical in applications where accurate measurements are critical, such as medical diagnostics and environmental monitoring. In this review paper, recent advances in different types of photonic sensors are discussed, which include photonic crystal-based sensors, surface plasmon resonance-based sensors, optical fiber-based sensors, optical waveguide-based sensors, and wearable sensors. These highly fascinating sensing devices play a crucial role in countless applications and have several advantages over traditional sensors. As technology continues to advance, we can expect photonic sensors to become even more precise, versatile, and reliable.

Photonic Crystal Hydrogels Fabricated from Nanoparticles of Fe3O4/SiO2 with Programmable Colors through Photopolymerization for Applications as Anticounterfeiting Applications

“…Besides, the longhorn beetles can change the color of their sheath wings from green to red when the ambient humidity increases. This is attributed to the alternative layers of photonic structures in their sheath-wing gas pedal. − Inspired by these interesting phenomena from nature, researchers have devoted significant efforts to developing responsive structural color materials that can change their color in response to external stimuli and have tried to apply these materials to various areas ranging from optical devices, color display printing, , colorimetric sensor , and detection to smart skin. , …”

On-Chip Photonic Detection Techniques for Non-Invasive In Situ Characterizations at the Microfluidic Scale

“…While the use of passive detection is circumscribed to samples presenting emission properties, active photonic detection schemes, in which samples are subject to interacting with a probing light beam, can be generally considered as non-invasive (i.e., they do not affect sample state), hence becoming of particular interest when they are applied to in operando studies. Additionally, they commonly offer a faster response time than electronic-based techniques while preserving a high sensitivity, which allows for high throughput and rapid analysis, and they are not susceptible to electromagnetic interference [ 32 ]. Moreover, photonic techniques allow for multiplexed detection of multiple parameters, valuable in complex sensing applications.…”

Advances in sensors using lossy mode resonances

“…Photonic sensor detection systems are attracting a great deal of interest and investment owing to their superior performance [1][2][3] and the utilization of intimate light-matter interactions is becoming more and more attractive for both chemical and bilogical detection of different species in size (from volatile compounds -VCs -to cells), at surprisingly low concentrations (attomolar or even further) [4]. Currently, photonic sensing systems are far from being exploited to their full potential and there is still a long way to go in the understanding of these phenomena in order to achieve so.…”
