With many potential applications in mind, great effort is being applied to develop a terahertz-wave technology platform on which waves can be manipulated with sufficient confinement and efficient ...

A two-dimensional periodic lattice of holes in a slab of material with a high refractive index, i.e., a photonic crystal slab (PCS), can exhibit a great number of ...

NTT scientists in Japan have used a photonic crystal to slow 1550 nm light down to 1% of its normal speed. The researchers first fabricated a two-dimensional silicon photonic crystal slab using ...

Cut snowflakes out of sheets of paper, and you've got a nice winter art project. Grow a microscopic sheet of silicon crystal studded with snowflake-shaped holes, and you've got the thinnest sonic ...
