چکیده

در سال‌‌های اخیر افزاره­های نوری مبتنی بر بلورهای فوتونی، به دلیل ویژگی‌‌های جالب بلورهای فوتونی مانند تلفات ناچیز، سرعت گروه بسیار پایین، انعطاف‌‌پذیری در شکل و ابعاد و همچنین مناسب بودن برای مدارهای مجتمع در ابعاد نانو، بسیار مورد توجه قرار گرفته‌‌اند. در این مقاله، با استفاده از بلورهای فوتونی دو بعدی، نحوه طراحی یکی از ضروری‌‌ترین عناصر مدارهای مجتمع نوری یعنی دی‌‌مالتی‌‌پلکسر تمام نوری بررسی شده است. برای این منظور ابتدا یک ساختار فوق‌‌العاده فشرده از دی‌‌مالتی‌‌پلکسرهای مبتنی بر تشدیدگرها مورد بررسی قرار گرفته و سپس با ایجاد دو خم 90 درجه با مهندسی در ساختار میله های دیواره خم، با عملکرد بالا در کانال­های خروجی،‌‌ میانگین بازده انتقال توان در یکی از کانال­ها 94.28% بدست آمده است.

چکیده [English]

In recent years, optical devices based on photonic crystals have received much attention due to valuable features of photonic crystals such as low losses, very low group velocity, flexibility in shape and dimensions as well as being suitable for integrated circuits in Nano-scale. In this paper, using two-dimensional photonic crystals, the design of optical de-multiplexer as one of the most essential elements of integrated optical circuits, is investigated. For this purpose, an ultra-compact structure of resonator-based de-multiplexers is demonstrated and then by creating two high performance 90° bends along with engineering in the structure of bending wall rods at the output channels, transmission efficiency average 94.28%  in one of the output channels has been obtained.
