Modern nanotechnology allows one to scale down various important devices (sensors,
chips, fibers, etc.) and thus opens up new horizons for their applications. The efficiency of …

The quest for all-optical signal processing is generally deemed to be impractical because
optical nonlinearities are usually weak. The emerging field of nonlinear photonic crystals …

In contrast to a conventional symmetric Lorentzian resonance, Fano resonance is
predominantly used to describe asymmetric-shaped resonances, which arise from the …

Electromagnetic cavity modes in photonic and plasmonic resonators offer rich and attractive
regimes for tailoring the properties of light–matter interactions, yet there is a disturbing lack …

Recently, strongly modulated photonic crystals, fabricated by the state-of-the-art
semiconductor nanofabrication process, have realized various novel optical properties. This …

Periodic nanostructures in photonics facilitate a far-reaching control of light propagation and
light–matter interaction. This article reviews the current status of this subject, including both …

We have demonstrated all-optical bistable switching operation of resonant-tunnelling
devices with ultra-small high-Q Si photonic-crystal nanocavities. Due to their high Q/V ratio …

A technique is demonstrated which efficiently transfers light between a tapered standard
single-mode optical fiber and a high-Q, ultra-small mode volume, silicon photonic crystal …

A theoretical formalism to calculate the spontaneous emission rate enhancement (Purcell
factor) and propagation mode β factor from single quantum dots in a planar-photonic-crystal …

Nanostructures that feature nonreciprocal light transmission are highly desirable building
blocks for realizing photonic integrated circuits. Here, a simple and ultracompact photonic …
