Fabrication of Nb<sub>2</sub>O<sub>5</sub> Waveguide and Switch for Visible Light Applications
Visible- light waveguides and thermo-optic switches were fabricated and demonstrated using Nb<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf>O<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</inf>. The propagation loss of rib waveguide was characterized. The thermo-optic switch achieved <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$\pi$</tex> phase shift and 6.5 dB extinction ratio at 635 nm.
