Making metals transparent, which could lead to fascinating applications, has long been pursued. Here we demonstrate that with narrow slit arrays metallic plates become transparent for extremely broad bandwidths; the high transmission efficiency is insensitive to the metal thickness. This work provides a guideline to develop novel devices, including(More)
In this review, we present our recent work on making structured metals transparent for broadband electromagnetic waves by surface plasmons (SPs) or spoof surface plasmons (SSPs). First, we demonstrate that the interference between the localized and propagating SPs plays an important role in the optical transmission through arrays of sub-wavelength holes.(More)

We report here an approach to tune efficiently the phase difference of light in two orthogonal directions, ϕ, by controlling the time retardation with a microstructured surface made of L-shaped metallic patterns. The time retardation through the judicious microstructures can be adjusted on the femtosecond level, and ϕ can be linearly tuned accurately from(More)
On-chip nanophotonics serves as the foundation for the new generation of information technology, but it is challenged by the diffraction limit of light. With the capabilities of confining light into (deep) subwavelength volumes, plasmonics makes it possible to dramatically miniaturize optical devices so as to integrate them into silicon chips. Here we(More)
