Design and Optimization of a Single-Mode Multi-Core Photonic Crystal Fiber With the Nanorod Assisted Structure to Suppress the Crosstalk

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...
