This paper reports on recent results on passively mode-locked InAs/InP quantum-dot-based lasers. These low-dimensional structures have proved very attractive in improving most of the properties of these devices. Subpicosecond pulse generation at repetition rates up to beyond 300 GHz has readily been demonstrated. Ultranarrow RF linewidths reach record… (More)
We report on subpicosecond pulse generation using passively mode locked lasers (MLL) based on a low optical confinement single InGaAsP/InP quantum well active layer grown in one epitaxial step. Systematic investigation of the performances of two-section MLLs emitting at 1.54 microm evidenced pulse width of 860 fs at 21.31 GHz repetition rate, peak power of… (More)
Several applications are pushing the development of high performance mode-locked lasers: generation of short pulses for extremely high bit rate transmission at 100 Gb/s and beyond, all-optical clock recovery at 40 Gb/s and beyond, generation of millimeter wave signals through mode-beating on a high speed photodiode, optical sampling for analog-to-digital… (More)
Error-free transmission over 50 km single mode fiber of 8 WDM ITU channels with 100 GHz channel spacing is demonstrated at 10 Gbit/s by using comb generation in a quantum dash mode-locked laser.
The application of a mode-locked quantum-dot Fabry-Perot (QD-FP) laser in a wavelength preserving all-optical 3R regenerator is demonstrated at 40 Gb/s. The 3R regenerator consists of a QD-FP laser for low-timing jitter clock recovery, cross-phase modulation based retiming, and self-phase modulation based reshaping. The performance of the alloptical 3R… (More)
We report for the first time on the systematic measurement of timing jitter of 40-GHz self-pulsating Fabry-Perot laser based on InAs/InP quantum dashes emitting at 1.55 microm. Two different methods, one based on optical cross-correlation and one on electrical spectrum sideband integration are used and show a good agreement, yielding a jitter of 0.86 ps in… (More)
We report on comb generation at 1.55 mum using a mode-locked quantum-dash-based laser. A flat optical spectrum with a ~10-nm width consisting of eight 100-GHz-spaced channels is demonstrated. Separate error-free transmission of each channel is achieved at 10 Gb/s over 50-km-long single-mode fiber. Compared to an ideal external cavity continuous-wave laser,… (More)
The performance of a quantum-dash Fabry-Pérot laser is experimentally characterized for 40 Gb/s RZ-DPSK and NRZ-DPSK clock recovery, 40 Gb/s RZ-OOK all-optical 3R regeneration, and 160 Gb/s OTDM sub-harmonic clock recovery.
This paper describes the application of a time-domain modeling approach for a laterally coupled distributed feedback (LC-DFB) semiconductor laser for the first time. We numerically study the effect of the radiation modes on LC-DFB laser properties. We integrate the Streifer's coefficients, which represent the effects of radiation and evanescent modes into… (More)
