We propose and design a novel homogeneous nanorod-assisted multi-core photonic crystal fiber (NA-PCF). and it utilizes the flexibility of photonic crystal fiber (PCF) for air-hole design. NA-PCF applied to multi-core fiber (MCF) communication system. High refractive index nanorods are introduced in the center of the seven cores which are further surrounded by a periodical arrangement ... https://spencertifieders.shop/product-category/bowling-balls/
