The Quantum Photonic Microscope is an autonomous unit, which allows the investigation of quantum optical phenomena of light-matter coupled quantum materials and cavity quantum electrodynamic systems, including single quantum dots and atomically thin crystals. It consists of a low vibration, helium-free cryostat, reaching a base cryogenic-temperature of 4K to host the sample. The cryostat will allow for optical excitation and detection in free space with sub-micrometer resolution. Optical excitation of the samples is facilitated by a frequency tunable, mode-locked hands-off laser system. Since we target the investigation of systems with resonant wavelengths in the spectral range between 680–1000 nm, this laser system is composed of a pump laser, and a Titanium-Sapphire Oscillator. The system is complemented by a measurement unit, which is composed of a standard spectrograph, which is equipped with a high sensitivity Si CCD detector, and a set of high sensitivity, low time-jitter single-photon detectors. The characteristic processes of quantum coherence in the samples which will be investigated on the sub 100 ps scale, calling for single photon detectors with a time-jitter, which is smaller than 50 ps throughout the spectral window of interest.
