| A graphene-based-hybrid plasmonic waveguide (GHPW) with a unique geometric structure is designed for surface plasmon polariton guidance and modulation at the frequency area of 10 to 30 THz. The GHPW consists of a graphene layer in the middle, a high-density polyethylene (HDPE) gating layer, two interior dielectric delimiter layers, and two exteriors semi-cylinder Germanium substrates symmetrically embedded on both edges of the graphene. Because of the matchless semi-cylinder structure design, the electromagnetic wave interaction with graphene ultimate subwavelength SPPs strong confinement with long propagation length. Small normalized mode area of ~10-4 and long propagation length of 10.67-28.92 μm at Fermi energy of 1.0 eV is attained for SPPs modes propagation of the GHPW in the frequency bound of 10-30 THz and semi-cylinder radius R > 450 nm, respectively. By controlling the graphene Fermi energy, it is found that the structure has a modulation depth higher than 20 % for the frequency band of 10-30 THz and arrives at the peak of approximately 100 % at a frequency greater than 28.75 THz. To benefit from the great broadband MIR propagation and modulation efficiency, the GHPW may promise different MIR waveguides, modulators, photonic, and optoelectronic devices. | ||

| چکیده [English] | ||
| یک موجبر پلاسمونیک هیبریدی مبتنی بر گرافن (GHPW) با ساختار هندسی منحصر به فرد برای هدایت و مدولاسیون پلاریتون پلاسمون سطحی (SPP) در محدوده فرکانس 30-10 THz طراحی شده است. این موجبر از یک لایه گرافن در وسط، یک لایه دریچه ای پلی اتیلن با چگالی بالا (HDPE) و دو لایه جداکننده دی الکتریک داخلی و دو زیرلایه ژرمانیوم نیمه استوانه ای تشکیل شده است که به طور متقارن در هر دو لبه گرافن تعبیه شده اند. برای انتشار مدهای SPP در ناحیه فرکانسی 10-30 تراهرتز، ناحیه مدی کوچک( 4-10~) و طول انتشار بلند (10.67-28.92 میکرومتر) در انرژی فرمی 1.0 الکترون ولت، بدست آمده است. با کنترل انرژی فرمی گرافن، مشخص شد که به ازای گستره فرکانسی 30-10 تراهرتز، این ساختار دارای عمق مدولاسیون بالاتر از 20 درصد است و در فرکانس بیشتر از 28.75 تراهرتز به بیشینه مقدار خود می رسد. موجبر پیشنهاد شده، نوید بخش بهره مندی از انتشار پهن باند با راندمان مدولاسیونی بالا، و ایجاد نسل متفاوتی از موجبرهای MIR، مدولاتورها، و دستگاه‌های فوتونیکی و نوری را می دهد. | ||
