Abstract
A method is provided for partially collecting light from a polymer waveguide (11, 56). A polymer waveguide (11, 56) is provided, through which a light signal (17) is traveling. A faceted groove (28) is placed in the polymer waveguide (11, 56), thereby reflecting a controllable portion of the light (22) that is traveling through the polymer waveguide (11, 56) from the facet (21) at an oblique angle. Typically, the reflected light is directed into a photodetector (24, 41), which is included into an integrated circuit (52, 53) on a substrate (51).
