Abstract

Design, fabrication and optimization of high refractive-index contrast Tantalum Pentoxide (Ta2O5) nanoscale waveguides are reported. The strong evanescent field in such nanoscale (150nm-250nm thick) and high-refractive index contrast (Delta.n ~ 0.65) waveguides provide an ideal integrated platform for cell/micro-particle guiding, sorting and diagnosis applications. Optical guiding velocity of 50µm/sec was obtained for 8µm microparticle with guided power of only 20mW.
