“…1, a finite-size periodic multilayers structure, consists in the form of (H)(LH)3(N-LC)(HL)3(H), where H = Si, L = Air and an N-LC layer of type (E7) embedded at the central defect. Assuming the anisotropic molecules' optical axis in the X-Z-plane, the N-LC medium dielectric tensor is given by [31]:…”

In this study, 1D Photonic Crystal (PhC) with Nematic Liquid Crystal (N-LC) central microcavity is analyzed and discussed using Rigorous Coupled Wave Analysis (RCWA) method. A microcavity is inserted into the 1D PhC by the Air Defect, making it ideal for measuring the properties of an N-LC contained inside the microcavity. Here simulation is considered for NLC (E7) as a thermal sensor. The principle of photonic crystal thermal sensor operation is studied in the TE mode of the incident beam. We conduct a detailed study of the thermal sensor with differences in the width of central microcavity of N-LC. The sensitivity and quality factor are evaluated. Compared to other photonic crystal sensors mentioned previously, this thermal optical sensor has a much simpler structure and higher sensitivity.

“…The integrated optical waveguide sensors in different structures have been reported recently, such as: the surface Plasmon resonator [1], Bragg grating based F-P microcavity [2,3], PhC microcavity [4,5], resonator based micro-disk [6,7], micro-ring resonator [8,9] and MZI [10,11]. Among these waveguide sensors, the MZI sensor has another highsensitivity device, which can be used as a biosensor.…”

In this paper, we have proposed a new design, to enhance and simulate a Highly Sensitive Mach-Zehnder Interferometer (MZI) Biochemical sensing platform using a Silicon Rib Waveguide. We considered two different MZI configurations: the first one with an S-bend & Y-junction and the second with an angular Y-junction. We determined the critical cut-off radius and the critical cut-off angle for the S-bend & Y-junction and the angular Y-junction configurations respectively. Based on the analyses of the evanescent field intensity, the mode polarization and cross section dimensions of the Silicon Rib waveguide are optimized using beam propagation method. The critical parameters of the design are calculated to ensure minimal optical losses and a new sensitivity value of 308 dB/RIU with a detection limit of 10-7, which shows the ability of the structure to produce biosensor.
