A tapered microfiber decorated with titanium dioxide-silicon dioxide nanocomposite saturable absorber (TiO2-SiO2-SA) is demonstrated via alkali fusion method and spin-coating technique. The TiO2-SiO2-SA exhibited 17.1% modulation depth, 31.7 μJ/cm2 saturation fluence and 35.4% non-saturable loss. Th...
