DNA has become one of the most extensively used molecular building blocks for
engineering self-assembling materials. DNA origami is a technique that uses hundreds of …

Concerns over possible toxicities of conventional metal-containing quantum dots have
inspired growing research interests in colloidal silicon nanocrystals (SiNCs), or silicon …

Many chemical methods have been developed to favor a particular product in
transformations of compounds that have two or more reactive sites. We explored a different …

Engineering the electromagnetic environment of a nanometre-scale light emitter by use of a
photonic cavity can significantly enhance its spontaneous emission rate, through cavity …

A nanolaser is a key component for on-chip optical communications and computing systems.
Here, we report on the low-threshold, continuous-wave operation of a subdiffraction …

Photons that have a helical phase front, that is, twisted photons, can carry a discrete, in
principle, unlimited, but quantized amount of orbital angular momentum (OAM). Hence …

Cavity quantum electrodynamics (QED) studies the interaction between a quantum emitter
and a single radiation-field mode. When an atom is strongly coupled to a cavity mode,, it is …

The effects of cavity quantum electrodynamics (QED), caused by the interaction of matter
and the electromagnetic field in subwavelength resonant structures, have been the subject …

We describe the recent experimental progress in the control of spontaneous emission by
manipulating optical modes with photonic crystals. It has been clearly demonstrated that the …

The most-awaited convergence of microelectronics and photonics promises to bring about a
revolution for on-chip data communications and processing. Among all the optoelectronic …
