This review covers the recent progress made in the photonic crystal-based sensing
technology for gas sensing applications. Photonic crystal-based sensing has tremendous …

A new biophotonic sensor composed of a porous silicon (PSi)-based one-dimensional (1D)
defective annular photonic crystal (APC) was designed and theoretically investigated using …

Surface acoustic wave (SAW) devices are widely used for signal processing, sensing and
increasingly for lab-on-a-chip applications. Phononic crystals can control the propagation of …

The geometry of photonic crystal waveguides with ring-shaped holes is optimized to
minimize dispersion in the slow light regime. We found geometries with a nearly constant …

Using the plane wave expansion method, we investigate the effects of structural parameters
on absolute photonic band gap (PBG) in two-dimensional honeycomb annular photonic …

A novel polarization beam splitter based on a silicon photonic crystal (PC) heterostructure
operating in the optical-telecommunications band is envisaged and is configured for planar …

Lithium niobate (⁠ LiNbO 3⁠, LN) is an important material which is widely applied in
fabricating photonic and acoustic devices. However, it is difficult to either wet etch or dry etch …

In this study, the reconfigurable biosensing capabilities of the one-dimensional annular
photonic structure,(AB) 5CDC (AB) 5, was examined theoretically. The proposed structure …

A system composed of air holes in a dielectric host to form two square photonic crystals, with
the same orientation and lattice constant but different scatterer radii, making an interface …

We demonstrate an effective method for realization of robust, tailorable annular plasma
photonic crystals (PPC) in dielectric barrier discharge with two water electrodes. Fast …
