Abstract
Aiming at fast detection speed and significant cost reduction, a photonic system exploring both wavelength- and time-division multiplexing is presented in this paper. The system is primarily consisted of a coherent dual electro-optical frequency comb which slices the broadband microwave spectrally in the optical domain, and an optical storage which snap-shots the input for later read-out. The proof-of-concept experimental setup measures a microwave burst of ~ 1 μs with up to 8 GHz bandwidth within 20 μs at ~ 1 MHz resolution, making the system especially attractive for a wide range of applications for microwave spectral analysis.
