Proposed fibre tapering using plasmonic microheaters and deformation-induced pull. (IMAGE)
Caption
a) Schematic of the experimental set-up, showing a pre-tapered fibre with a metal plate attached to it inside an SEM chamber. The modulated light is guided into the fibre via an optical-through-vacuum connector. The light-thermal effects are monitored in real-time with nanometre precision. The insets sketch the stress distribution and temperature profile of the fibre in selected regions; the positive normal stress denotes tensile stress, and Tg represents the glass transition temperature. b1) SEM image of a gold plate attached on a pre-tapered fibre. b2) SEM image and measured profile of the as-fabricated fibre drawn from b1.
