Frequency-dependent linewidth enhancement factor of optical injection-locked quantum dot/dash lasers.

چکیده
Combining theoretical and experimental studies show that optical injection strongly changes the behavior of the linewidth enhancement factor (α(H)-factor) and the FM-to-AM indices ratio (FAIR) in quantum dash/dot semiconductor lasers. In contrast to solitary lasers, both the α(H)-factor and the FAIR at low-frequency modulation are reduced by optical injection. At high modulation frequency, however, the phase-amplitude coupling characteristics are little influenced by optical injection.

Bandwidth enhancement of Fabry-Perot quantum-well lasers by injection-locking
Theory and experiment for dc and small-signal electrical modulation of an injection-locked quantum-well (QW) Fabry-Perot laser are presented. Our experiment is realized by performing side-mode injection locking of a multiple-quantum-well (MQW) InGaAsP FabryPerot (FP) laser, which has the advantage of optical wavelength conversion. We first measure the dc characteristics and optical spectra of a...
متن کاملModulation properties of optically injection-locked quantum cascade lasers.
A rate equation analysis on the modulation response of an optical injection-locked quantum cascade laser is outlined. It is found that the bifurcation diagram exhibits both bistable and unstable locked regions. In addition, the stable locked regime widens as the linewidth enhancement factor increases. It is also shown that both positive and negative optical detunings as well as strong injection...
متن کاملOptical linewidth of a passively mode-locked semiconductor laser.
We measured the optical linewidths of a passively mode-locked quantum dot laser and show that, in agreement with theoretical predictions, the modal linewidth exhibits a parabolic dependence with the mode optical frequency. The minimum linewidth follows a Schawlow-Townes behavior with a rebroadening at high power. In addition, the slope of the parabola is proportional to the RF linewidth of the ...
متن کاملTuning of the critical feedback level in 1.55-μm quantum dash semiconductor laser diodes
The onset of the coherence collapse regime, which is incompatible with data transmission, is investigated both theoretically and experimentally in a 1.5-μm InAs/InP quantum dash semiconductor laser. It is numerically shown that the excited state filling produces an additional term, which accelerates the route to chaos. The paper also experimentally shows that the linewidth enhancement factor ca...
متن کاملEnhanced Modulation and Noise Characteristics in 1.55 µm QD Lasers using Additional Optical Pumping
The modulation response, relative intensity noise (RIN) and frequency noise (FN) characteristics of quantum dot (QD) lasers are investigated theoretically in the presence of an external optical beam. Using small signal analysis of the rate equations for carriers and photons, it is demonstrated that by injecting excess carriers into the QDs excited state through optical pumping, the modulation r...
