This study investigates semiconductor optical amplifiers for high-speed communication, evaluating gain, power consumption, and phase modulation. Using the Fourth-Order Runge-Kutta method, it models amplifier dynamics and simulates signal amplification. Quantitative results indicate the system attains a maximum gain of 46.44 dB, significantly improving the input signal. The output power is recorded at 144.71 mW, highlighting the amplification process's impressive efficiency. In addition, a phase shift of −9.6 radians has been witnessed, clarifying the degree of phase modulation imparted by the semiconductor optical amplifier. The resulting phase modulation is a critical component in maintaining signal integrity, especially in systems requiring tight phase control. The study demonstrates that semiconductor optical amplifiers achieve high gain with low power consumption, while effective phase modulation improves overall system performance. Numerical simulations provide valuable insights for designing energy-efficient, high-performance semiconductor optical amplifiers, supporting advancements in high-speed optical communication technologies through optimized amplifier performance.
