Hollow Core Antiresonant Fiber With Radially Asymmetric Nodeless Claddings

We propose and numerically study a novel type of hollow core antiresonant fiber.with a single layer of nodeless radially asymmetric cladding tubes, i.e., the cladding tube.presents a bulb-like shape, that the local cladding curvature radius at the core/cladding.boundary is larger than the other side
