There has been an increasing interest in all-optical analogues of electromagnetically
induced transparency and Autler–Townes splitting. Despite the differences in their …

We demonstrate that the above-threshold behavior of a laser can be strongly affected by
exceptional points which are induced by pumping the laser nonuniformly. At these …

This review is focused on the latest developments in continuous-wave (CW) photomixing for
Terahertz (THz) generation. The first part of the paper explains the limiting factors for …

Nanophotonics is where photonics merges with nanoscience and nanotechnology, and
where spatial confinement considerably modifies light propagation and light-matter …

Photonic molecules (PMs) are artificial nanoscale photonic structures that play important
roles in the fundamental optics field. PM quantum optics has recently become a promising …

This chapter reviews the fundamental optical properties and applications of photonic
molecules (PMs)–photonic structures formed by electromagnetic coupling of two or more …

We report on the first experimental demonstration of terahertz (THz) whispering-gallery
modes (WGMs) with an ultra-high quality factor of 1.5× 10 4 at 0.62 THz. The WGMs are …

Identifying the mode numbers in whispering-gallery mode resonators (WGMRs) is important
for tailoring them to experimental needs. Here we report on a novel experimental mode …

We propose a dielectric rod waveguide antenna (DRW) integrated with a photomixer as a
THz emitter. This represents a different approach as opposed to the classical solution of a …

We design, fabricate, and characterize the terahertz integrated resonators on the silicon
platform. Based on mode analysis and selection, the high-Q feature of resonators made of …
