Facilities

We operate three separate labs dedicated to quantum optics and spectroscopy of solid-state materials. Each is stabilised in temperature and humidity and designed specifically for experiments in low-light conditions.

You can visit our lab on this page. Please select “Physics, Photonics and Quantum sciences”.

 

The labs are fitted with state-of-the-art equipment, meticulously selected for low-light experiments:

  • Three Attocube Attodry cryostats. The Rolls-Royce of helium-free cryostats for confocal microscopy and solid-state physics, equipped with superconducting magnets and XYZ piezo motors and scanners to allow for all the freedom you need to explore your sample.
  • High grade tunable lasers. Of all kinds to use the wavelength you need for the experiment you need from 400 to 1350 nm.
  • State-of-art detectors and spectrometers. Detecting single photons is not straightforward but we use liquid nitrogen cooled cameras and superconducting single photon detectors to make the most challenging experiments possible, from visible light to telecom wavelengths.
  • Radiofrequency equipment to detect spin signals through optically detected magnetic resonance.
  • Optics and optomechanics are mostly custom-built from top grade components for our bespoke experiments.
  • And much more: time-tagging high speed electronics, ultra-high resolution wavemeters, Fabry-Perot interferometers, electro-optic modulators, lock-in amplifiers, pulse-pattern generator, etc.

We also have a newly refurbished clean-room which is fully equipped with modern nano-fabrication and characterization equipment. The EPSRC Two-Dimensional Photonics Fabrication facility is also located here. Please contact Prof. Gerardot for access to the facility (there is a generous pump-priming scheme!).

  • Scanning Electron Microscopes / Electron-beam lithography / Focused Ion Beam lithography;
  • Optical lithography facility including a Direct Laser Writer and Mask aligners;
  • Semi-automatic flip-chip bonder; Plasma etcher (ICP/RIE); Electron beam evaporator; Thermal evaporator;
  • Atomic Force Microscope; ZYGO interferometer, a Dektak profilometer, several optical micorsocpes;
  • A homemade setup for 2D materials fabrication (all-dry) in an inert environment and an imaging ellipsometer enabling characterization of 2D materials and thin films.
