摘要

Abstract

In recent years

the two-dimensional (2D) transition metal dichalcogenides (TMDCs) have attracted renewed interest owing to their remarkable physical and chemical properties. Similar to that of graphene

the atomic thickness of TMDCs significantly limits their optoelectronic applications. In this study

we report a hybrid WS

-optical-fiber-nanowire (WOFN) structure for broadband enhancement of the light–matter interactions

i.e.

light absorption

photoluminescence (PL) and second-harmonic generation (SHG)

through evanescent field coupling. The interactions between the anisotropic light field of an optical fiber nanowire (OFN) and the anisotropic second-order susceptibility tensor of WS

are systematically studied theoretically and experimentally. In particular

an efficient SHG in the WOFN appears to be 20 times larger than that in the same OFN before the WS

integration under the same conditions. Moreover

we show that strain can efficiently manipulate the PL and SHG in the WOFN owing to th

e large configurability of the silica OFN. Our results demonstrate the potential applications of waveguide-coupled TMDCs structures for tunable high-performance photonic devices.
