Finite-Difference Time-Domain Simulation of Light Propagation in 2D Periodic and Quasi-Periodic Photonic Structures

پالس هاي خيلي كوتاه يك فناوري اميدبخش براي انتقال فوق سريع اطلاعات است كه با افزايش تقاضا براي تبادل اطلاعات از طريق سيستم هاي ارتباطي نوري مورد توجه قرار گرفته است. ما يك مرور كلي از پيشرفت هاي نظري عددي در يك مدلسازي عددي معادله‌هاي ماكسول براي شناسايي پخش پالس هاي ليزري كوتاه در ساختارهاي فوتوني تهيه كرديم. فرايند پخش پالس نور كوتاه در ميان ساختارهاي فوتوني دوره اي دوبعدي و شبه دوره اي براساس محاسبات Finite-Difference Time-Domain از معادلات ماكسول شبيه سازي شده است.

Ultra-short pulse is a promising technology for achieving ultra- high data rate transmission which is required to follow the increased demand of data transport over an optical communication system. Therefore, the propagation of such type of pulses and the effects that it may suffer during its transmission through an optical waveguide has received a great deal of attention in the recent years. We provide an overview of recent theoretical developments in a numerical modeling of Maxwellʹs equations to analyze the propagation of short laser pulses in photonic structures. The process of short light pulse propagation through 2D periodic and quasi-periodic photonic structures is simulated based on Finite-Difference Time-Domain calculations of Maxwell’s equations.
