In this research, we propose and analyse a two-dimensional photonic crystal having L-
shaped bend waveguide to realise a negligible bending loss, nonlinearity and confinement …

In this paper, a 60 waveguide bend is designed in a two-dimensional (2D) photonic crystal
(PC) slab to provide high transmission over a large bandwidth. We apply geometrical …

In this paper, a high-efficiency 60° photonic crystal (PC) bend geometry is proposed. The
corresponding PC is a two-dimensional triangular lattice of air holes in a dielectric slab. In …

The application of the photonic crystal (PC) waveguide (WG) as the light delivery system in
the heat‐assisted magnetic recording (HAMR) system is demonstrated. The structure …

The transmission characteristics of various bent periodical dielectric waveguides (PDWGs)
are analyzed by the finite-difference time-domain (FDTD) method in this work. The bending …

There are several key factors that affect the transmission characteristics of the 90°(L-shaped)
bent photonic crystal waveguides. The first factor is the direct coupling efficiency from the …

A conventional photonic crystal waveguide (PCWG) has been fabricated by constructing a
large bulk of periodical rods (or holes) and omitting those on the desired optical paths. Thus …

A highly efficient Y-junction based on a planar photonic crystal (PhC) platform is presented.
The PhC consists of a triangular array of holes etched into GaAs/AlGaAs heterostructure …

In this paper, a new all-optical switching structure is proposed and analyzed. Switching is
accomplished by embedded Kerr nonlinear rods in the coupling region of a photonic crystal …
