Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment. Such a gatekeeper would enable powerful and ...

Bound states in the continuum (BICs) are a special class of resonant states. Although they have the same momentum and energy as the propagating modes in free space, yet they are not coupled to the ...

While I try to keep up with the industry by reading many of the trade publications, I never fail to learn new principles and tips from DesignCon. At DesignCon 2012, among insights gained, was the ...

Bloch surface waves are electromagnetic modes confined to the interface of one‐dimensional photonic crystals, where a periodic arrangement of dielectric materials creates an optical band gap that ...

(a) Total internal reflection of two Bloch waves at the interface of the photonic crystal. (b) Guidance condition: as a Bloch wave reflects twice, it duplicates itself. (c) Conventional and ...
