Optical nanofibre applications from atomic physics through to quantum optics
(QSense OIST Mini Symposium Talk 4)​

Ultrathin optical fibres, with diameters on the order of the propagating light wavelength, have already proven their versatility across a variety of different areas, such as sensing, particle manipulation, cold atom physics, and in photonics. The intense evanescent field and very steep field gradient are some of the main advantages offered by these systems as it allows us to achieve ultrahigh light intensities that may otherwise not be attainable in a standard laboratory. In this talk, I will present work conducted at OIST related to the fields of atomic physics and quantum optics. For example, we embed ultrathin fibres into a laser- cooled sample of rubidium atoms for studies related to Rydberg atom formation near a dielectric surface and to study degenerate and nondegenerate two-photon processes. In another example, I’ll discuss work on structured ultrathin fibres that combine a Bragg grating with a cavity for enhanced photon coupling from a quantum emitter. Overall, the versatility of these fibres for many different experimental platforms – particularly if one goes beyond the basic, single mode fibre design – will be promoted.

OIST Mini-Symposium for Quantum Sensors of Magnetic and Inertial Forces

This mini-symposium is hosted by the Quantum Machines Unit in the Okinawa Institute of Science and Technology Graduate University, and will take place from Feb 1, 2021 - March 5, 2021. To get the precise schedule and zoom invitation please register below. Attendance is open to any student/faculty member from any of the institutions associated with the speakers.


Quantum systems are extremely fragile, sensitive to noise and fluctuations by their environments. This, in turn, makes them excellent sensors for a variety of forces and fields. In this mini-symposium we focus on the development of novel quantum sensors which are aimed at the precision sensing of inertial forces such as acceleration or gravity, and magnetic forces.

Such sensors - accelerometers/gravimeters or magnetometers, have a widespread application in industry such as sensing underground water movements using gravimeters, through to magnetic brain imaging using magnetoencephelography. Each week we hear from three international experts on these topics in hour-long seminars and discussions.
