Comparative investigation og hydrogen bonding in silicon based PECVD grown dielectrics for optical
(Elsevier, 2004-06)Silicon oxide, silicon nitride and silicon oxynitride layers were grown by a PECVD technique. The resulting refractive indices of the layers varied between 1.47 and 1.93. The compositional properties of the layers were ... -
Low loss optical waveguides and polarization splitters with oxidized AlxGa1-xAs layers
(Bilkent University, 1998)Low propagation loss waveguides, operating at 1.55 fim optical wavelength, are fabricated utilizing oxidized AhGai_a;As layers. MBE grown multilayer semiconductor heterostructures are characterized before and after ... -
Plasma enhanced chemical vapor deposition of low loss as-grown germanosilicate layers for optical waveguides
(2004)We report on systematic growth and characterization of low-loss germanosilicate layers for use in optical waveguides. Plasma enhanced chemical vapor deposition (PECVD) technique was used to grow the films using silane, ... -
Silicon-on-insulator optical waveguides and waveguide devices
(Bilkent University, 2000)Silicon-on-insulator(SOI) optical waveguides, directional couplers and some types of MMI couplers were designed, fabricated and characterized at a wavelength of 1.55 /im. Effective index method and the single mode ...
