Subpicosecond electrical pulse generation using photoconductive switches with long carrier lifetimes
(AIP Publishing, 1989-03-13)
Using a new mechanism of electrical pulse generation, we have generated 350 fs (full width at half maximum) electrical pulses on a coplanar transmission line, fabricated on an unimplanted silicon-on-sapphire substrate.
Nonlinear picosecond-pulse propagation through optical fibers with positive group velocity dispersion
(American Physical Society, 1981-09-28)
The predictions of the nonlinear Schrodinger equation have been tested by passing 5.5-psec optical pulses through a 70-m single-mode optical fiber. With use of a precise cross correlation technique based on pulse compression, ...
Optical pulse compression based on enhanced frequency chirping
(AIP Publishing, 1982-07-01)
Through numerical simulations, we show that, under relatively general conditions, passage of an intense picosecond pulse through a single-mode optical fiber can cause the pulse to become strongly frequency broadened with ...
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 ...
Simultaneous optical pulse compression and wing reduction
(AIP Publishing, 1986-03-31)
We report the compression of picosecond optical pulses with a simultaneous reduction of the pulse wings by using a combination of both the self-phase modulation and nonlinear birefringence effects in a modified optical-fiber ...
