A fiber-optics system is experimentally demonstrated for real-time identification of an optical energy-spectrum pattern based on dispersion-induced time-to-spectrum convolution, providing an output power above a prescribed threshold when the incoming spectrum matches the programmed driving pattern in a temporal modulator, avoiding spectral detection and post-processing.
All-optical reconfigurable time-to-frequency conversion and temporal magnification of optical waveforms is proposed and experimentally demonstrated using a XPM-based time lens by exploiting chirp rates being directly proportional to the peak power of a parabolic pump pulse.
A system is proposed for all-optical reconfigurable time-to-frequency (T-to-F) conversion and temporal magnification of optical waveforms using a design based on a cross phase modulation-induced time lens combined with group-velocity dispersion. In this design, the T-to-F conversion ratio and magnification factor can be easily tuned by exploiting the direct dependence of the time-lens chirp with the...
A novel approach to perform time-domain spectral shaping (TDSS) is demonstrated, enabling fast-reconfigurable truly arbitrary (complex-valued, non-symmetrical) pulse shaping/coding using a setup similar to previous (intensity-only, symmetrical) TDSS schemes.
A fiber-optic programmable picosecond pulse shaper is experimentally demonstrated using multi-level phase-only linear filtering in the time-domain, enabling the synthesis of high- quality, fully arbitrary temporal intensity profiles, including asymmetric waveforms and high-speed pulse-amplitude code sequences.
Parabolic pulses with durations ranging from the picosecond to the sub-nanosecond range (100-ps reported here) were generated through frequency-to-time mapping. A virtual timelens was applied in the spectral shaping stage in order to relax the constraints imposed by the far-field condition.
