Using quantum dots to produce a CMOS terahertz camera and polarimeter
Quantum dots can convert terahertz photons into visible light. This mechanism is used to develop a semiconductor-based room-temperature terahertz camera that can simultaneously record the field strength and polarization states of a terahertz beam. The proposed detector has fast speeds and can be manufactured at the wafer-scale.

Observation of inhomogeneous plasmonic field distribution in a nanocavity
The strength of the plasmonic field between a plasmonic particle and a Au surface can be measured at ~2-Å resolution by following the Raman peaks of a suitably labelled self-assembly monolayer.

Deterministic coupling of site-controlled quantum emitters in monolayer WSe2 to plasmonic nanocavities
An array of Au nanocubes combined with a planar mirror simultaneously induces single-photon emitters at lithographically defined locations in WSe2 and enables directional outcoupling of Purcell-enhanced single photons with high quantum yield.
