We report the generation of time- and wavelength-interleaved optical pulses using the principle of sub-harmonic pulse gating in a dispersion-managed fiber cavity. The pulsed source has been applied to the processing of electrical and optical signals including analog-to-digital conversion, wavelength multicast, and serial-to-parallel optical data conversion.

In this paper, we present a new electro-optic (EO) probing system based on heterodyne detection. The use of a recirculating frequency shifter allows to expand the bandwidth of the system far beyond what is attainable with a conventional heterodyne EO set-up. The performance for the frequencies up to 50GHz is analysed to forecast the viability of the system up to the THz range.
