Liu %A Mazur, E. %X We report on the assembly of low-loss silica nanowires into functional microphotonics devices on a low-index non-dissipative silica aerogel substrate. Using this all-silica technique, we fabricated linear waveguides, waveguide bends and branch couplers. The devices are significantly smaller than existing comparable devices and have low optical loss, indicating that the all-silica technique presented here has great potential for future applications in optical communication, optical sensing, and high-density optical integration. %B Nano Lett. %V 5 %P 259–262 %G eng %U /files/mazur/files/rep_486.pdf %R 10.1021/nl0481977
