Abstract
All optical analog-to-digital converter consisting of an optical polarization modulator using nonlinear phase shift and switches based on polarization is proposed. The principle of operation is discussed using Jones matrix. Optical polarization states through the system and limit of resolution are evaluated. The resolution is optimized by maintaining the polarization state in the converter and refining the polarization of incident sampling signal. Parallel usage of converter modules is proposed to increase the dynamic range, where cyclic nature of optical phase plays an important roll. Application to photonic routing of our converter is also proposed.
