Abstract

We propose a simple and efficient light launch scheme for a helical-core fiber (HCF) by using an adiabatically tapered splice technique, through which we overcome its inherent difficulty with light launch owing to the large lateral offset and angular tilt of its core. We experimentally demonstrate single-mode excitation in the HCF in this configuration, which yields the coupling efficiency of around −5.9 dB (26%) for a ~1.1-μm light input when the splice joint is tapered down to 30 μm in diameter. To our knowledge, this is the first proof-of-principle report on the fusion-splice coupling between an HCF and a conventional single-mode fiber.

Schematic of the proposed light launch scheme into a helical core fiber via an ATS. Through the successive mode conversion along the adiabatic taper [LP01core(SMF) → LP01taper(SMF) → LP01taper(HCF) → LP01core(HCF)], the coupling efficiency between the conventional SMF and the HCF can be significantly improved. The images in the lower part represent some typical mode field patterns along the ATS sections.
