Semiconductor mode-locked lasers as pulse sources for high bit rate data transmission

High performance InAs/InP quantum dot 34462-GHz C-band coherent comb laser module

“…However, these techniques either require complex setups, high pump powers with finely tuned operating parameters, or they provide only a limited number of spectral carriers. For practical systems, a compact, low-cost, energy-efficient semiconductor comb laser is desired [10][11]. Furthermore, some of the new transmission schemes also require that the wavelength channels are mutually coherent, or locked together in phase.…”

Dynamical regimes in a monolithic passively mode-locked quantum dot laser

“…Mode-locking (ML) in lasers is a powerful tool for generating short optical pulses for different practical applications ranging from high speed communication to medical diagnostics. In particular, monolithic passively modelocked semiconductor lasers are compact sources of picosecond pulses with high repetition rates suitable for applications in telecommunication technology [1,2]. Recently a new generation of mode-locked semiconductor lasers based on quantum dot (QD) material was developed [3].…”

DFB Laser Diode Dynamics with Optoelectronic Feedback

“…Where f min and f max are the boundary of the frequency range. For a pulsed source with a pulse interval of 80ps, the maximum tolerated rms jitter for sampling application is 120th the pulse interval according to (Jiang, 2005) which lists the requirements for such application leading to maximum tolerated rms jitter of 667fs while our calculated jitter shown in figure 22is around 150fs which is well below the limits required for photonic ADC sampling application. In addition to the compactness of our proposed solution, this performance exceeds fiber laser performance where according to (Chen, 2007).…”
