We report on the use of the atomic layer deposition (ALD) process for fabricating liquid core antiresonant reflecting optical waveguides (ARROWs). The ALD permits the deposition of a very conformal sub-100-nm titanium dioxide antiresonant layer. This results in a low loss liquid core ARROW waveguide with a broadband output transmission spectrum. Optical transmitted spectrum from the fabricated structure has been reported, and the measured attenuation losses agree with the theoretical predictions.

Abstract
We report on the use of the atomic layer deposition (ALD) process for fabricating liquid core antiresonant reflecting optical waveguides (ARROWs). The ALD permits the deposition of a very conformal sub-100-nm titanium dioxide antiresonant layer. This results in a low loss liquid core ARROW waveguide with a broadband output transmission spectrum. Optical transmitted spectrum from the fabricated structure has been reported, and the measured attenuation losses agree with the theoretical predictions.File in questo prodotto:
