چکیده

در این مقاله به آموزش مبتنی بر نرم‌افزار یک دی‌مالتی‌پلکسر چهار کاناله کریستال فوتونی با استفاده از نرم‌افزار آرسافت پرداخته شده است. آموزش ساختار دی‌مالتی‌پلکسر بر مبنای خصوصیات یک فیلتر کریستال فوتونی بنا نهاده شده‌ است. در این تجزیه و تحلیل با تغییر شعاع میله‌های درون نانو‌تشدیدگر حلقوی و شعاع میله‌های پراکندگی در ساختار کریستال ‌فوتونی، پارامتر مهم طول‌موج مرکزی 1573.6 نانومتر در فیلتر بهبود یافته است. از مزایای دی‌مالتی‌پلکسر چهار کاناله می‌توان به میانگین ضریب‌کیفیت 4525 و میانگین ضریب انتقال توان کانال‌ها %95 و میزان بیشینه و کمینه هم‌شنوایی کانال‌‌ها به ترتیب -19.6 دسی‌بل و -40.4 دسی‌بل و میانگین عرض کانالی 0.375 نانومتر اشاره کرد. می‌توان از دی‌مالتی‌پلکسر‌های چهار کاناله پیشنهاد شده در سامانه‌های مخابراتی بهره برد. با توجه به ضرورت آموزش فناوری‌های جدید، آموزش مبتنی بر نرم‌افزار و ارائه مراحل طراحی چنین ساختارهایی به منظور توسعه و بهبود آن‌ها بسیار حائز اهمیت است. از این‌رو، در این مقاله به ارائه سرفصل مربوطه برای دانشجویان کارشناسی ارشد مهندسی الکترونیک پرداخته می‌شود. این مبحث می‌تواند به عنوان بخشی از درس بلورهای فوتونی و یا درس فوتونیک در نظر گرفته شود.

چکیده [English]

In this paper, simulation-based (software-based) teaching of a 4-channel optical demultiplexer based on photonic crystal is presented by using the R-Soft software. The teaching of the demultiplexer structure is based on the use of a photonic crystal filter. In this analysis, with the variation of the radius of the cylindrical nano-ring resonator and the radius of the scattering rods, the critical length parameter of 1573.6 nm is improved in the design of the filter. The advantages of the 4-channel demultiplexer include the mean quality factor of 4525, mean channel power transfer factor of 95%, and maximum and minimum channel cross-talk of -19.6 and -40.4, respectively. Also, mean channel width is obtained as 0.375 nm. Moreover, the proposed 4-channel demultiplexer can be used in WDM systems. The simulation-based teaching of these structures is very important to develop and improve the multiplexers performance. Therefore, the related syllabus is suggested for master of science (MSc) students in Electronic Engineering major. This syllabus can be considered as a part of Photonic Crystal or Photonics courses.
