“…In practical applications, as the light-matter interactions rely on the strength of the interaction between the optical field and the material, many nonlinear phenomena will be enhanced under the presence of slow light, which allows us to design miniaturized and high-sensitive devices based on this field enhancement [114][115][116]. In 2012, F. Hosseinibalam et al [117] proposed a slow light assisted PCC for ultracompact, low power, and high-sensitive biosensor. The proposed biosensor was composed of a half-ring cavity that is side-coupled to an optofluidic slow light PCW (see Fig.…”

This review covers photonic crystal cavities (PCCs) and their applications in optical sensors, with a particular focus on the structures of different PCCs. For each kind of optical sensor, the specific measurement principle, structure of PCC, and the corresponding sensing properties are all presented in detail. The summary of the reported works and the corresponding results demonstrate that it is possible to realize miniature and high-sensitive optical sensors due to the ultra-compact size, excellent resonant properties, and flexibility in structural design of PCCs. Finally, the key problems and new directions of PCCs for sensing applications are discussed.

“…To overcome this problem in the context of miniature absorption spectroscopy devices, photonic crystal (PhC) based gas sensors have been proposed [4]- [6]. In particular, miniaturized devices based on slow-light PhC waveguides offer an fascinating solution for achieving high performance in nonlinear optics process and sensing applications both in refractive index sensing and absorption spectroscopy [7]- [10]. The slow-light regime increases a device's effective optical length as well as the light intensity inside it, enhancing light-matter interactions [11].…”

A tunable slow-light hollow-core photonic crystal fiber (HPCF), applicable to miniaturized microstructure spectroscopic gas sensors is proposed. In the proposed structure, we have taken the advantage of the microfluidic infiltration technique to tune the slow-light regime so as to match the reference absorption line of the target gas sample, which is required for designing miniaturized gas sensors with reconfigurable detection sensitivity. The main feature of this structure is that the enhanced electrical field is strongly localized in the hollow-core of a photonic crystal fiber for any gas samples due to tunability of slow-light modes. We discuss the potential of slow light in HPCF for realizing compact and tunable gas sensor devices with low and high loss material. In particular, we present numerical results showing how this optofluidic microstructure can be used for detecting CO, CO 2 , H 2 S, CH 4 , SO 2 , and N 2 O gases.Index Terms-Hollow-core photonic crystal fiber, micro structure gas sensor, slow-light, microfluidic.

“…Correspondingly, the novel properties of slow light can be exploited in a wide range of potential application areas such as optical integrated circuits and controlled enhanced lightmatter interaction [5,6]. Furthermore, the devices based on the slow-light effect can be utilized in different applications including modulators, optical switches, biosensors, phase shifters, and data storage devices [7][8][9][10][11].…”

A new type of wideband slow light with a large delay bandwidth product in a slab photonic crystal waveguide with a triangular lattice of circular air holes in a silicon-on-insulator substrate based on optofluidic infiltration is demonstrated. It is shown that dispersion engineering through infiltrating optical fluids-with different refractive indices n(1f) and n(2f)--in the first two rows of the air holes innermost to the waveguide results in an improved normalized delay bandwidth product ranging from 0.187 to 0.377 with large bandwidth (12 nm<Δλ<32 nm) and group index (14.20< n(g)< 24.62) around 1550 nm. The nearly zero group velocity dispersion on the order of 10-(20) s(2)/m is achieved in all of the structures. These results are obtained by numerical simulation based on a three-dimensional-plane-wave expansion method.
