OPERA-photonics

The OPERA-photonics group hosts a state-of-the-art optics laboratory well equipped to work in the near and short-wave infrared (from 700 up to 2300 nm). It has multiple laser sources (CW and pulsed mode locked) and fibre amplifiers, devices for the temporal, spectral and spatial analysis of laser beams, and for the manipulation of optical and electrical signals with, amongst others: Detectors up to 60 GHz that can be coupled to 50GS/s oscilloscopes or to spectrum analysers; Amplitude and phase high frequency optical modulator (10-40GHz); Autocorrelators covering the picosecond and femtosecond ranges, around 800 nm, 1550 nm and 2200 nm, with FROG capabilities around 800 nm and 1550 nm; Optical spectrum analysers covering the wavelength range 650–‒2600 nm; PM fibre splicer and material to couple light in and out of guiding structures such as fibres or photonic nanowires. A multiphoton-microscope working around 800 nm is also available.The quantum optics capability include cryogenically cooled superconducting detectors, single photon avalanche photodiodes, photon pair sources, and time tagging electronics.
