Abstract

Atomic layer deposition (ALD) is a promising method to grow optical materials on waveguide structures. Propagation loss analysis indicates that amorphous TiO2 and Al2O3 films are promising for the waveguide purposes.
Instead, polycrystalline ZnO does not work properly as a waveguide by itself, but the waveguiding properties can probably be enhanced by introducing intermediate Al2O3 layers. The wide variety of available materials, conformal growth properties and low scattering losses of many ALD films enable their usage in various waveguide applications.
Experimental coating of silicon waveguides is discussed.
