We theoretically investigate the frequency shift of a free-running semiconductor laser when optically injected by an optical frequency comb. By numerical integration of the laser rate equations, we have identified two types of frequency shifts, frequ

A system framework of wideband optical frequency comb (OFC) with coincident polarization is numerically analyzed based on a gain-switched vertical-cavity surface-emitting laser (VCSEL) subject to orthogonal optical injection. In the structure, the VC

In a laser diode (LD) system with optical injection, the effects of gain saturation of the LD on the orbital instability of the system are analyzed numerically. For the optical injection LD system without signal application, it is shown that the effe

For silicon-based epitaxial quantum dot lasers (QDLs), the mismatches of the lattice constants and the thermal expansion coefficients lead to the generation of threaded dislocations (TDs), which act as the non-radiative recombination centers through

The study theoretically investigates the dynamic of an injection-locked semiconductor laser with zero linewidth enhancement factor. The stability map of the injection locking process is drawn, and bifurcation diagrams are generated. Carrier density d
