In the present work, we give a hydrostatic pressure sensor based on two micro-cavities
coupled to a photonic crystals waveguide. A dual asymmetric H1 incorporing each one a …

Colour patterns based on micro‐nano structure have attracted enormous research interests
due to unique optical switches and smart surface applications in photonic crystal …

In this work, we design a new biosensor concept that uses a microcavity in 2D photonic
crystal (PhC) to sense small refractive index (RI) changes. The RI sensor is formed by a …

Detection of bio-alcohol is crucial in diverse industries, including forensics, medicine, and
food production. This paper presents a novel biosensor for bio-alcohol detection in water …

We propose a temperature sensor design based on the two-dimensional (2-D) photonic
crystals (PhCs) microcavity coupled to two waveguides. We consider a Si 2-D PhC, and the …

In this paper, a high-performance 4-channel demultiplexer (DEMUX) based on 2D photonic
crystal using three cascaded ring resonators is proposed. The proposed DEMUX is …

In this work, we design a new pressure sensor based on two-dimensional photonic crystal
waveguide coupled to a point-defect resonant microcavity. The mechanism of sensing is …

Toxic gas has a median fatal concentration in the oxygen of much more than 200 parts per
million (ppm) but far less than 2000 ppm by volume of gas. Many industries, mines and …

Using the three-dimensional finite difference time domain method (3D FDTD) with perfectly
matched layers (PML), optical and magneto-optical properties of two-dimensional magneto …

Photonics crystal sensors, sensitive to light, play a crucial role in discerning minute
alterations in a material's refractive index, finding widespread application, such as in …
