Abstract Controlling the temporal evolution of an electromagnetic (EM) wave’s frequency components, the so-called time-frequency (TF) distribution, in a versatile and real-time fashion remains very challenging, especially at the high speeds (> GHz

We demonstrate gapless and real-time spectral analysis of broadband waveforms with >250 analysis points per spectrum. The concept is based on a discretization of an electro-optic time-lens to implement a phase modulation equivalent to 206.25π.

We experimentally demonstrate electronically programmable, user-defined time-varying frequency filtering of continuous broadband signals, over a 22 GHz frequency tuning range and with >1 GHz reconfiguration speed, using electro-optic modulation of a
