Description

technical field [0001] The invention relates to the field of microwave photonics, more specifically to an optical quantizer for high-speed modulation of nonlinear harmonic characteristics of an optical emitting device for analog-to-digital conversion. Background technique [0002] High-speed, high-precision quantizers are essential core devices in the fields of radar, high-performance computing, communications, and high-speed instruments. With the rapid development of information technology in recent years, although traditional quantizers relying on electronic technology have been developing, due to the limitations of low bandwidth and fuzzy comparator judgment, the development is very slow and it is difficult to meet need. Compared with traditional electrical quantizers, optical quantizers have advantages such as high resolution, fast sampling rate, high stability, and anti-electromagnetic interference, and have attracted much attention in recent years. In recent years, m...
