“…The growing demand for optical sensing applications has raised the significance of PhC-based optical technologies. Due to the PBG property and the light confinement capability of the PhC-based structures, PhCs and their applications in healthcare, 116 – 120 RI sensing, 121 – 124 quality control of food, 125 – 128 and in many other fields 129 – 132 is now the sphere of interest for researchers in the present era (Table 3).…”

The idea of photonic crystal came to be when E. Yablonovitch and S. John recommended a structure in 1987 having periodic alteration of refractive index in one or multiple directions. Photonic crystals have the potential to manipulate and tailor the flow of light across the crystal, which gives advantage to invent many photonic devices on the microscopic scale having very small footprints. In recent years several articles have been published on the advances of photonic crystal-based structures. This review article mainly focuses on the several fabrication techniques of photonic crystals and their applications in different fields. Several photonic crystalbased structures such as logic gates, optical sensors, polarization beam splitters, and absorbers for solar cells are reviewed in this paper to show recent advancements on this trending topic. Also, a brief review of the different steps of fabrication of photonic crystals and different fabrication methods proposed by researchers is articulated in this paper.

In this paper we investigate a new design of high sensitivity photonic crystal temperature sensor (PCTS). A square lattice of silicon (Si) rods immersed in air matrix is used as a basic structure. The designed sensor consists of two inline quasi-waveguides which are coupled to a resonant cavity (RC). The sensing principle is based on Si refractive index change caused by the variation of the temperatures over a range from 0 to 80 • C. This variation leads to an important shift in the resonance wavelength. The performance of the suggested temperature sensor has been analyzed and studied using finite-difference time domain (FDTD) method. The results show that our designed structure offers a high sensibility of 93, 61 pm/ • C and quality factor of 2506.5. Its structure is very compact with total size 115.422 µm 2 , which is suitable for nanotechnology based sensing applications.
