Abstract/Summary:
The primary objective of this work was to build optical waveguide structures based on amorphous Aluminum Nitride (AlN) to study the coupling of short optical pulses into optical waveguides and their subsequent propagation through the waveguides and interfaces.;A thin film of amorphous Aluminum Nitride, (AlN), was used as waveguide core, which was deposited by reactive plasma sputtering on various substrates, such as silicon and soda-lime glass to characterize their performance. Structures on AlN deposited thin film were built, by photolithography with negative photoresist and chemical etching with Sodium Hydroxide, (NaOH).;Material characterization of deposited AlN, was performed. Electrical and optical properties were established. An attenuation rate of 0.09 dB/cm was determined at a wavelength of 1550 nm, and 0.22 dB/cm at a wavelength of 650 nm.;The soliton is a very short light pulse that can be generated in optical fiber. It was proposed to launch solitons in AlN. Analysis proved that its dispersion has a rossover point at around 1550 nm, which would allow bright solitons to exist.
