چکیده

گیت‌‌های نوری به عنوان عنصری پایه‌‌ای، نقش مهمی را در توسعه ریزپردازنده‌‌ها و حافظه‌‌های نوری بر عهده دارند. در این تحقیق، از تشدیدکننده‌‌های ریز حلقه در طراحی واحد منطقی بازآرایی‌پذیر استفاده شده است. تشدیدکننده ها از جنس GaAs/AlGaAs هستند. در پیکربندی پیشنهاد شده، با استفاده از اتصال موازی هفت تشدیدکننده ریز حلقه و انتخاب خروجی های مناسب، عملگرهای منطقی اساسی سه ورودی پیاده سازی شده است. از یک لیزر سبز به عنوان پمپ نوری در تزریق نور به ریز حلقه و تغییر ضریب شکست ماده استفاده شده است که باعث جابه‌‌جایی طول‌‌موج تشدید ریزحلقه‌ها به مقدار 1.5 نانومتر خواهد شد. نتایج شبیه‌‌سازی قابلیت ساختار پیشنهادی در ایجاد توابع منطقی سه ورودی را تایید می کنند. ازاین ‏رو می توان از این ساختار در طراحی مدارهای مجتمع نوری بهره برد. امکان بازآرایی ساختارجهت تغییر عملگر، افزایش سرعت پردازش و بهبود کیفیت تفکیک سطح صفر و یک، از مزایای ساختار معرفی شده است.

چکیده [English]

Optical gates as basic elements play an important role in the progress of all optical microprocessors and memories. In this paper, GaAs/AlGaAs microring resonators have been used to design and analysis of reconfigurable optical gates. By using parallel coupled microring resonators, based on the suggested configuration and selecting appropriate output, all three input logical functions would be achieved. A green LASER has been used to inject light to microring resonator and change the refractive index of the microring resonator that would make resonance wavelength shift of 1.5 nm. Simulation results properly verify the ability of the proposed structure to extract all three input logical functions. As a result, it could be used to design optical integrated circuits. The advantages of the proposed structure are its reconfiguration capability that could be used as various gates, its integrating capability and high extinction ratio between zero (0) and one (1) of logical levels.
