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. | ||
