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.}, doi = {10.1021/nl0481977}, url = {/files/mazur/files/rep_486.pdf}, author = {L.
