Seminarium Optyczne

We bring super-resolution methods known from imaging to the spectral domain and demonstrate aspectrometer that operates beyond the Fourier limit. The spectrometer is based on a quantummemory with built-in processing capabilities, that implements a time-axis inversion interferometerallowing optimal measurement for two closely-spaced spectral lines. This is accomplished byengineering a frequency-dependent dispersion combined with time-dependent temporal phasemodulation that allows us to split, rotate and interfere the signal pulses in the chronocyclic space.Analysis based on quantum metrology shows the advantage of our technique over bothconventional spectroscopy as well as heterodyne measurements
