2Low-loss silicon core fibre platform for mid-infrared nonlinear photonics显示文摘Broadband mid-infrared light sources are highly desired for wide-ranging applications that span free-space communications to spectroscopy.In recent years,silicon has attracted great interest as a platform for nonlinear optical wavelength conversion in this region,owing to its low losses(linear and nonlinear)and high stability.However,most research in this area has made use of small core waveguides fabricated from silicon-on-insulator platforms,which suffer from high absorption losses of the use of silica cladding,limiting their ability to generate light beyond 3μm.Here,we design and demonstrate a compact silicon core,silica-clad waveguide platform that has low losses across the entire silicon transparency window.The waveguides are fabricated from a silicon core fibre that is tapered to engineer mode properties to ensure efficient nonlinear propagation in the core with minimal interaction of the mid-infrared light with the cladding.These waveguides exhibit many of the benefits of fibre platforms,such as a high coupling efficiency and power handling capability,allowing for the generation of mid-infrared supercontinuum spectra with high brightness and coherence spanning almost two octaves(1.6-5.3μm).Haonan Ren Li Shen Antoine F.J.Runge Thomas W.Hawkins John Ballato Ursula Gibson Anna C.Peacock 2019Light(Science & Applications)2019,8,1:0
