  • Abstract ABSTRACT
      In this thesis, the K+-Na+ ion-exchanged technique is used to fabricate waveguide structures on soda-lime glasses. This technique has the advantages such as simple treatment, low loss and low cost, and very well performance for the channel waveguide to fiber coupling due to very small refractive index difference between the glass and the fiber materials.
      In our experiment, we use Inductively Coupled Plasma Reactive Ion Etching (ICP-RIE) dry etching system and difference etching gas compositions of SF6/ Ar/ H2/ O2 to etch soda-lime glass for fabricating channel waveguide. By changing the reactive gases flow rate, ICP power, Bias power and the composition of H2/ O2. The experiments have been carried out to investigate the optimal performance parameters of the etching rate, etching profile, anisotropy and surface roughness for soda-lime glass substrates.
      For the plasma etching system has lots advantages such as high resolution, well selectivity, faster etching rate, independence control of power and anisotropy etching. The experiment results show that the maximal etching rate is up to 100 nm/min and the maximal depth is 2 µm with vertical sidewall profile at SF6 flow rate of 100 sccm, O2 flow rate of 10 sccm, total chamber pressure of 10 mtorr, ICP power of 500W and Bias power of 100W.
