Coherent coupling of a single molecule to a scanning Fabry-Perot microcavity

Physicists in many research areas aim to realize efficient devices that can generate intricate quantum states and perform complex operations. Considering that photons are ideal carriers of quantum information while material...[more]


Biexciton emission strongly enhanced by plasmonic nano-cone

Semiconductor quantum dots (Q-dots) are desirable in many applications because they can emit multiple photons for each excitation pulse via the generation of multiple excitons. In practice, however, multi excitonic emissions are...[more]


A single molecule as a high-fidelity photon-gun for producing intensity-squeezed light

Generation of light with intensity fluctuations below the shot-noise limit has been one of the most important challenges in quantum optics. An elegant approach was proposed in the 1980s: through excitation of a two-level atom, a...[more]


Cryogenic optical localization provides 3D protein structure data with Angstrom resolution

Starting with efforts in scanning nearfield optical microscopy in the 1980s, many laboratories around the world have contributed to pushing the resolution of optical imaging beyond the Abbe limit [1]. A particularly fruitful...[more]


Nonlinear optics with a single molecule and only a few photons

Photons do not usually interact. This is why in linear optics two laser beams can cross without clashing like two swords. In nonlinear optical materials, however, photons can interact with one another, opening the...[more]

Nanostructures and quantum emitters together make light more precise

Optical fibre sensors make use of diverse physical effects to measure parameters such as strain, temperature and electric field. We have recently introduced a new class of reconfigurable fibre sensor, based on a ‘flying-particle’...[more]


When every photon counts

Single-photon sources are desirable resources for a variety of applications, ranging from quantum information processing to metrology.  A single emitter, like a single atom or a quantum dot can, in principle, be used as the...[more]


A cantilever-based sub-λ3 mode-volume optical microcavity

Microcavities have been popular for a number of applications, ranging from micorlasers, cavity quantum electrodynamics studies and sensing. The enhanced coupling in the cavity is usually achieved via a high quality factor. This,...[more]
