AB - Unlike LEDs emitting a broad light spectrum, semiconductor lasers send a narrow, coherent beam, allowing for more efficient and stable data transmission over longer distances. Semiconductor laser technology offers a significant advantage in optical communications systems in its ability to provide precise tuning of the intensity and wavelength angle. This tuning can be achieved by automatically controlling the current within a grid-distributed Bragg reflector (SGDBR) structure. This technology enhances transmission characteristics by enabling homogeneous integration of the laser beam and the fundamental mode angle in the core of the multimode fiber. This integration perfectly aligns the optical signal within the fiber structure, significantly reducing loss and dispersion. Furthermore, semiconductor lasers effectively address the problem of power loss due to sharp bending, reducing it to negligible levels while offering a wider bandwidth and higher speed than other methods. Experimental results for 60m plastic and 300m glass multimode fibers showed a bit error rate of 10–7 and 8 × 10–4, a quality factor (Q-factor) of 5.122 and 3.1, and a signal-to-noise ratio of 8 and 25, respectively. The measured performance is stable even with mechanical shortcomings such as fiber bending and shaking.
