Title:
Y-JUNCTION REFLECTOR TUNABLE DELAY OR RESONATOR WAVEGUIDE DEVICES
Document Type and Number:
WIPO Patent Application WO2005120194
Kind Code:
A3
Abstract:
The invention provides tunable delay or resonator devices in an electro optical substrate (12). Signals in at least one waveguide (16, 34, 68) in the electro optical substrate pass through Y -junction reflectors (18, 20, 32, 78) which direct signals from one branch of the waveguide back into another branch of the waveguide. A coupled delay or resonator approximated loop is presented in an embodiment of the invention with opposing Y -junction reflectors. In other embodiments of the invention, a delay ladder is provided with selectable levels of delay from multiple outputs.
