Query: Design, Fabrication, and Characterization of Ta2O5 Photonic Strip
  Waveguides   Efficient coupling of single quantum emitters to guided optical modes of
integrated optical devices is of high importance for applications in quantum
information science as well as in the field of sensing. Here we present the
design and fabrication of a platform for on-chip experiments based on
dielectric optical single-mode waveguides(Ta2O5 on SiO2). The design of the
waveguide is optimized for broadband (600-800 nm) evanescent coupling to a
single quantum emitter (expected efficiency: up to 36%) and efficient off-chip
coupling to single-mode optical fibers using inverted tapers. First test
samples exhibit propagation losses below 1.8 dB/mm and off-chip coupling
efficiencies exceeding 57%. These results are promising for efficient coupling
of solid state quantum emitters like NV- and SiV-centers to a single optical
mode of a nanoscale waveguide.
