Abstract
High-resolution jitter measurement is essential for the next generation of electronic communications and sensor systems. However, most electrical timing jitter measurement equipment has a low resolution because of the limitations of electronic processing accuracy. Meanwhile, photonics-based jitter measurement methods have a higher resolution but cannot measure the widely used electrical signals. This work proposes a potential high-resolution jitter measurement method for electrical signals based on the photonics time stretch technique. The jitter information can be magnified in the optical domain and then measured by electrical equipment. The experimental results demonstrate that the jitter of an electrical pulse is magnified from 59.02 ps to 663.29 ps when the magnification factor is 11.24.
