“…PhCs based on cholesteric LCs could present basic elements of optical integrated circuits due to their optical birefringence [18]. In addition, it could be the cornerstone of many modern optical applications such as, phototriggered photonic actuators [19], optical diodes [20], thermal sensing [1,21], stress sensor [22], polarization rotator [23], optical switches and filters [24,25], electro-optical tunable devices [26] and biosensing applications [27].…”

In this work, we present a simple design to act as a temperature sensor based on the well-known one dimensional photonic crystal. The main idea of the proposed sensor is essentially depending on the inclusion a defect layer of graphene monolayers deposited on nematic liquid crystal through the photonic crystal. The transfers matrix method, Kubo-Formula, and fitting experimental data represent the core axes of our theoretical treatment. Here, our design is prepared to sense temperature based on the shift of the resonant peak with the temperature variation. The performance of such sensor is demonstrated by calculating the sensitivity, figure of merit, detection limit, sensor resolution and the quality factor. The effect of the thickness of the defect layer and the mode of polarization as well on the performance of our sensor is investigated. The numerical results show that our sensor could be of interest in many fields of application due to the high values of its sensitivity and quality factor. The proposed sensor could provide a sensitivity of 4 nm °C−1 and quality factor up to 11000.

“…High nonlinearity [9], large mode field area [10], highly birefringence [2], and zero-flattened dispersion [11] characteristics have gained by modifying the design of PCF. Distinctive background materials such as Tellurite [12], Topas [13], and Silica [14] are also applied to improve the guiding properties of PCF. As a result, PCF can be utilized in the nanoparticle detection [15], humidity measurement [16], atom-atom interaction [17], micro-organism growth detection [18], bacteria detection [19], air pollution monitoring [14], gas leak detection systems with high accuracy and safety [20], environmental studies [21], sensing [22], and communication systems [23] for its unique optical properties.…”

Abstract:In this paper, a hexagonal shape photonic crystal fiber (H-PCF) has been proposed as a gas sensor of which both micro-structured core and cladding are organized by circular air cavities. The reported H-PCF has a single layer circular core which is surrounded by a five-layer hexagonal cladding. The overall pretending process of the H-PCF is completed by using a full vectorial finite element method (FEM) with perfectly matched layer (PML) boundary condition. All geometrical parameters like diameters and pitches of both core and cladding regions have fluctuated with an optimized structure. After completing the numerical analysis, it is clearly visualized that the proposed H-PCF exhibits high sensitivity with low confinement loss. The investigated results reveal the relative sensitivity of 56.65% and confinement loss of 2.31×10 5 dB/m at the 1.33-m wavelength. Moreover, effective area, nonlinearity, and V-parameter of the suggested PCF are also briefly described.
