Dark-pulse propagation in optical fibers
(American Physical Society, 1988-01-04)
We report measurements of the reshaping of 0.3-psec dark pulses due to their passage through 10 m of single-mode optical fiber. The measurements were performed as a function of intensity and the observed strong reshaping ...
Point source terahertz optics
(AIP Publishing, 1988-10-17)
We demonstrate an ultrafast 10 micro-m sized, electric dipole source of terahertz radiation closely coupled to a 1 cm spherical mirror. This optical approach has the advantages of subpicosecond response times with essentially ...
Measurement of ultrafast hot-carrier relaxation in silicon by thin-film-enhanced, time-resolved reflectivity
(AIP Publishing, 1988-01-04)
Time-resolved reflectivity measurements within ~100 fs resolution have revealed an initial 350 fs relaxation time in silicon, believed to be the time it takes hot, photoinjected carriers to relax to the band edge. The ...
