“…On the other hand, by adjusting the structural parameters of PC or infiltrating suitable materials in the air holes of PC, the propagation of light can be modified and engineered at will. Therefore, many PC based devices have been widely used in the applications of light flow control, such as filters [7,8], electro-optical modulators [9,10], switches [11,12], and delay devices [13]. Specially, PC based sensors seem to be much more popular due to their promising characteristics like ultra-compact size, high measurement sensitivity, flexibility in structural design, and more suitable for monolithic integration [14][15][16].…”

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.

This paper proposes a hexagonal photonic crystal fiber (H-PCF) structure with high relative sensitivity for liquid sensing; in which both core and cladding are microstructures. Numerical investigation is carried out by employing the full vectorial finite element method (FEM). The analysis has been done in four stages of the proposed structure. The investigation shows that the proposed structure achieves higher relative sensitivity by increasing the diameter of the innermost ring air holes in the cladding. Moreover, placing a single channel instead of using a group of tiny channels increases the relative sensitivity effectively. Investigating the effects of different parameters, the optimized structure shows significantly higher relative sensitivity with a low confinement loss.

“…Typically, PC is having PBG, which is entirely broken by introducing either line defect or point defect. By breaking the defects, PC based optical devices, such as filter [14,15], directional coupler [16], demultiplexer [17,18], triplexer [19,20], power splitter [21,22], logic gates [23], switches [24,25], electro-optical modulators [26,27], add-drop filter [28,29], and sensors [30][31][32][33][34][35][36][37][38][39][40][41], were reported.…”

Photonic sensing technology is a new and accurate measurement technology for bio-sensing applications. In this paper, a two-dimensional photonic crystal ring resonator based sensor is proposed and designed to detect the glucose concentration in urine over the range of 0 gm/dl-15 gm/dl. The proposed sensor is consisted of two inverted "L" waveguides and a ring resonator. If the glucose concentration in urine is varied, the refractive index of the urine is varied, which in turn the output response of sensor will be varied. By having the aforementioned principle, the glucose concentration in urine, glucose concentration in blood, albumin, urea, and bilirubin concentration in urine are predicted. The size of the proposed sensor is about 11.4 m×11.4 m, and the sensor can predict the result very accurately without any delay, hence, this attempt could be implemented for medical applications.
