Abstract

In this work, we investigate the effects of laser linewidth and detector bandwidth on signal behavior using the powerful homodyne technique, which allows us to obtain both amplitude and phase information about a signal. We analyze the impact of these parameters on signal distortion, noise, and phase errors, as well as their impact on the speed of random signal generation. Our Simulation results highlight the importance of carefully selecting laser linewidth and detector bandwidth for optimal signal performance. These findings have practical implications for a wide range of applications, including Quantum random number generation, telecommunications, radar systems, and optical sensing.
