“…We note that all the experimental studies of plasmonic and photonic materials discussed below were concerned with performance in the visible wavelength range (320 to 800 nm); however, some reported performance studies in the near-IR region (800 to 1700 nm) where the absorption line of CH 4 , hydrogen fluoride (HF), and NH 3 is present. 192 4.1 Nanoparticles Spherical particles have been utilized to fabricate photonic materials for sensing applications, for which the size of the particle plays a direct role in the optical properties observed. Spherical colloidal particles have been shown to exhibit angle-dependent structural colors caused by Bragg diffraction with optical properties affected by the size of the particles synthesized.…”

We review progress in the development of photonic platforms for detecting gases. Unlike sensors based on conventional refractive and diffractive optics, photonic sensors detect analytes using light-matter interactions of periodic nanostructures, plasmonic interactions, or combinations of the two. This summary focuses on the work done in the last two decades, and earlier reports are summarized in several authoritative reviews. Specifically, we focus on the research of bio-inspired photonic and plasmonic material fabrication, experimental studies, and theoretical studies for gas detection applications. In areas where reports are scarce, challenges are identified, and reports are included that may not directly relate to bio-inspired gas detection applications but nonetheless offer findings that can facilitate progress within underexplored areas of bioinspired gas sensing.

“…The relative sensitivity can be calculated through the following equation 24 r=nsRe(neff)f,where ns is the refractive index of the target gas is near 1, and Re(neff) is the real part of the effective mode index. Here, f is the fraction of the cavity power by the total optical power, which can be defined by 25 f=holes∫Re(ExHy−EyHx)dxdytotal∫Re(ExHy−EyHx)dxdy,…”

.One of the modern ways to diagnose diseases is through exhale gas of patients, which is non-invasive and therefore desirable to doctors. The composition of exhaled breath contains valuable information for identifying hyperbilirubinemia disease. The accumulation of bilirubin and its lack of excretion causes jaundice, and the production of bilirubin has a direct relationship with exhaled carbon monoxide (CO). A CO diagnostic sensor based on a photonic crystal fiber (PCF) that can detect hyperbilirubinemia has been designed. This method can be used repeatedly to detect and treated jaundice in time. The PCF is designed as a hexagon. The holes in the cladding are circular and the holes in the core are circular and oval. Finite element method is used to do all the numerical simulations. COMSOL Multiphysics software was used to obtain the results. In this setup, CO absorption wavelength is 1.567 μm, and the relative sensitivity of 64.28% is reported with confinement loss of 3.81 × 10 − 3 dB / m.

Photonic crystal applications and their high performance led them to be considered as a promising research area. The factors that affect their operation are the topology type, and the arrangement of its rod position, and their constructed materials. OR gate is proposed in this paper to be simulated and evaluated. This design is built on a square lattice-photonic crystal construction. Sensitivity analysis, and carefully rod locations are considered to obtain remarkable performance. Minimum size is the main property that distinguishes this design.Based on the simulations, a minimum size of 39.6 μm 2 is obtained. The bit rate of 3.2 Tb/s is calculated for this structure. The considered threshold power level is 0.25. Comparison table is well organized for the recently published photonic crystal OR-gate that is based on ring resonator topology. Finite difference time domain and plane wave expansion method are used to analyze the proposed structure at 1.55μm wavelength to verify ORgate operation. The fabrication methods are discussed and evaluated. As will be shown the size is decreased by around 23% of the recently published paper.
