Abstract In 1987, Yablonovitch and John proposed an artificial dielectric structure known as
Photonic crystals (PhCs) consisting of periodic and random variation of the refractive index …

In contemporary science and technology, photonic sensors are essential. They may be
made to be extremely resistant to some physical parameters while also being extremely …

Spatial overlap between the electromagnetic fields and the analytes is a key factor for strong
light‐matter interaction leading to high sensitivity for label‐free refractive index sensing …

In contrast to a conventional symmetric Lorentzian resonance, Fano resonance is
predominantly used to describe asymmetric-shaped resonances, which arise from the …

Two photonic crystal optical refractive index sensors have been proposed in this paper.
These sensors can be used for detection of basal cell cancer. A rod-type square lattice of …

We propose an ultrasensitive tunable terahertz (THz) sensor which consists of single-layer
graphene-based gratings integrated with a Fabry–Perot cavity through numerical simulation …

Optical biosensors are increasingly being considered for lab-on-a-chip applications due to
their benefits such as small size, biocompatibility, passive behaviour and lack of the need for …

We present an ultrasensitive tunable terahertz (THz) sensor that comprises monolayer
graphene-based gratings integrated with a Fabry-Perot (FP) cavity through precisely …

For non-invasive detection, terahertz (THz) sensing shows more promising performance
compared to visible and infrared regions. But so far, figure of merit (FOM) of THz sensor has …

Slotted photonic crystal waveguides (SPCWs) were designed to act as refractive index
sensing devices at mid-infrared (IR) wavelengths around λ= 3.6 μm. In particular, effort was …
