Microfluidic and bio-applications of optical microfibres

“…1) Flame-brushing [2] 2) Modified flame-brushing [3] 3) Self-modulated taper-drawing [4] 4) Micropipette puller [5] The vast majority of OMs reported in the literature have been manufactured using the "flame-brushing" technique, which was originally developed for the fabrication of optical fibre tapers and couplers and relies on a small flame which travels along an optical fibre under longitudinal stress. The profile of the tapered fibre can be controlled with an extreme accuracy by finely controlling the flame movement and the fibre elongation.…”

“…1) The "self-modulated taper-drawing" [1] 2) The flame-brushing technique [2][3][4][5][6] 3) The modified flame-brushing technique [9,12,13] 4) Direct pull from bulk glass [14] The "self-modulated taper-drawing" [1,15] was the methodology firstly published in Nature in 2003. It is a twostep procedure: firstly, a taper with a diameter of few micrometers is drawn from an optical fibre using the conventional flame brushing technique; then, the manufactured taper is cut into two halves in the uniform waist region, and one of the microfibers is wrapped onto a hot sapphire rod and pulled to sub-micrometric diameters.…”

Packaged chalcogenide microsphere resonator with high Q-factor

“…A silica taper with a $2 lm waist diameter was fabricated using standard 125 lm diameter telecommunication optical fiber (Corning SMF-28) by the modified flame brushing technique. 17 The microsphere, positioned on a glass slide, was coupled to the tapered fiber as shown in Figure 2(a). The tapered fiber was then connected to a tunable laser source and an InGaAs detector.…”
