The College of Education for Pure Sciences at the Department of Physics at the University of Basra organized a scientific lecture on (a theoretical study of the optical frequency comb in semiconductor lasers using the techniques of quality factor control, pattern stabilization and optical pumping)
The lecture presented by the researcher (Saja Jaafar Maatouk) included a numerical simulation of the generation of optical frequency comb in semiconductor lasers using
Three techniques: Q-switching, Mode-locking, and
Optical injection. injection (locking) Characteristics of the optical frequency comb produced by . were studied

These techniques for semiconductor laser work length
The study demonstrated the possibility of forming an optical frequency comb in semiconductor lasers using the three techniques
And the characteristics of the comb depend on the technique used, as it was noted that the frequency comb characteristics were adopted
Optical control of both the shutter opening and closing (F) cycles in the QF technique and along the bore length
Laser (L) in pattern stabilization technology and on optical pumping ratio (Iinj) and phase difference (AF) and on enhancing the display
Line (a) when using the optical injection technique.
The study proved that the frequency interval trep of the frequency comb depends on the technique used, and that the symmetry of the . distribution
The comb on both ends of the central frequency can disappear when the optical pumping ratio is increased or the boost value is high
The line width, the study also proved that the value of the phase difference affects the distribution of the teeth of the optical frequency comb.
