We describe a highly flexible ultrashort optical pulse source capable of generating duration-
tunable pulses at single or multiple wavelengths. The technique we report is based on the …

A simple, stable, and tunable optical pulse source emitting 3.2 ps pulses at a 10 GHz
repetition rate is presented. The pulses are obtained through soliton-assisted time-lens …

We demonstrate an all-optical scheme to multiply the repetition frequency of a high-rate
optical pulse train by using a spectral filter to remove unwanted frequency components. A …

Optical transmission systems exceeding 100 Gbit/s per channel require a clock pulse
generator with a repetition frequency corresponding to the bit rate. Since it is difficult, based …

We describe mode-locked fiber lasers in the GHz region and their applications to high-
speed optical communication such as soliton and tera bit/s OTDM transmission. As for the …

Electroahsorption (EA) modulators have been shown to have modulation depths of> 30dB
and, when driven sinusoidally at multigigahertz frequencies, to produce short pulses with …

Tunable short-pulse generation in the spectral range 1030–1330 nm with an all-fibre source
is demonstrated. A compact system with a femtosecond Yb fibre oscillator and a photonic …

We demonstrate 40-GHz soliton pulse train generation using nonlinear compression of the
output of a Mach-Zehnder modulator. This source generates transform-limited pulses at …

The compression of higher order solitons in a standard singlemode fibre followed by a short
dispersion decreasing fibre enables the high quality compression of pulses as broad as 21 …

We present a laser system capable of producing 190 femtosecond pulses at a repetition rate
of 20 GHz. The spectral masking of a phase modulated diode laser is used to produce a …
