Abstract
Add-drop filters are demonstrated using silica-on-silicon optical wave guide technology. This device consists of a full directional coupler s ubdivided by Mach-Zehnder sections. Tapering of the coupling coefficie nts is experimentally shown to dramatically reduce the filters' sidelo bes. Only one photolithographic step is required using the silica plan ar waveguide technology, yielding accurate wavelength control of the f ilters. Excellent agreement between measurement and design was achieve d.
