"spatio-temporal modulation effects on femtosecond SPP pulses... in either space or time domain, the proposed method offers potentially a variety of novel effects in SPP modulation especially associated with the temporal domain, thereby improving the degree of freedom of optical modulation and providing a new platform for on-chip spatiotemporal manipulation of optical pulses with applications including ultrafast on-chip photonic information processing, ultrafast pulse/beam shaping, and optical computing"
