Abstract :
A study of integrated optic devices based on adiabatic principles is reported. The components are a 3-dB coupler, a full coupler, a polarization splitter, a wavelength multiplexer, and two mode shape transformers. All components were fabricated from doped silica and silicon nitride films on silicon substrates. Results are given for an adiabatic full coupler and an adiabatic 3-dB coupler, an asymmetric Y-coupler for a 1.3-1.55- mu m-wavelength multiplexer, and a tapered waveguide for mode shape transformation.<>
