Sharifi Assistant Professor, Department of Computer Engineering, Vali-e-Asr University of Rafsanjan, Rafsanjan, Iran Journal Article 2020 03 02 The evolution of photonic crystal technology has catalyzed advancements in optical signal processing, particularly through the integration of nonlinear ring resonators. This literature review synthesizes recent research findings related to the development of all-optical photonic crystal decoders, emphasizing their potential applications and identifying significant knowledge gaps that warrant further exploration. In this paper, a photonic crystal structure for designing an all-optical decoder using a ring resonator is proposed. The proposed structure employs a nonlinear ring resonator with nano-silicon crystal material for switching operations. The structure is simulated using the finite-difference time-domain (FDTD) method and the plane wave expansion (PWE) method. This logic gate operates at a rate exceeding 660 gigabits per second. https://www.tmachineintelligence.ir/article_208995_1cdef448045c62522c83b8e9b3f532d2.pdf
