In this paper, a novel all-optical analog-to-digital converter (AOADC) is proposed and simulated for proof of principle. This AOADC is designed to operate in the range of telecom wavelength (1550 nm). A cavity made of nonlinear Kerr material in photonic crystal (PhC), is designed to achieve an optical analog-to digital conversion with 1 Tera sample per second (Ws) and the total footprint of 42 mu m(2). The simulation is done using finite-difference time domain (FDTD) method. (C) 2017 Elsevier Ltd. All rights reserved.
