Creating novel liquid crystalline (LC) photonic metamaterial structures is a highly promising
approach for the development of tunable photonic devices particularly when nanoporous …

Electrically controlled beam steering behaviors in a 2D square photonic crystal (PC)
composed of Si cylinders surrounded by nematic liquid crystal are studied. The results show …

In this paper, we propose two types of all-dielectric polarization-independent graded index
annular flat lens with a wide operating frequency range. The lenses are composed of two …

In this paper, we perform numerical analyses on polarization-independent and tunable
graded index lenses based on two-dimensional graded photonic crystals and utilizing liquid …

In this letter, ultra-fast pulse compression capacity of a triangular corrugated photonic crystal
(PhC) was investigated through the finite difference time domain method. The group velocity …

The efficient lens-to-waveguide light coupling has been an important issue in integrated
