Abstract
An integrated optics chip (70) includes an optical waveguide network (11) formed on a surface (106) of a substrate (72) formed of an electrooptically active material. The optical waveguide network (11) has an input facet (86) where an optical signal may be input to the optical waveguide network (11) and an output facet (88) where optical signals may be output from the optical waveguide network (11). A trench (74) is formed in the bottom surface (80) of the substrate and arranged to extend into the substrate toward the optical waveguide network (11). The trench (74) prevents light rays incident thereon from inside the substrate (72) from propagating to the output facet (88). In particular, the trench (74) prevents light scattered at the input facet (86) or from scattering centers in the optical waveguide network (11) from reflecting from the bottom surface (80) of the substrate (72) to the output facet (88). A cover (78) may be mounted to the top surface (106) of the substrate (72) to provide structural strength to the integrated optics chip (70). One or more side grooves (143, 144) may be formed in the sides of the substrate (72) and cover (78). A light absorbing material may be placed in the trench (74) and grooves (143, 144). A plurality of electrodes (150) may be formed on the substrate (72) adjacent the optical waveguide network (11), and a plurality of access electrodes (158, 160) may be formed on sides of the substrate (72) and cover (78) to provide electrical signals to the electrodes (150).
